Fix prettier formatting in base installer test

- Refactor setJavaDefault to delegate shared output/env logic to
  setJavaEnvironment, avoiding duplication between the two.
- Document that set-default applies to all JDKs in a multiline
  java-version, and that installed JDKs remain registered in Maven
  toolchains regardless of set-default.

When `false`, `JAVA_HOME` and `PATH` are not updated, but `JAVA_HOME_<major>_<arch>` is still set so the JDK remains discoverable. Default value: `true`.

 **NOTE:** Oracle JDK 17 licensing varies by patch level. As shown on the [JDK 17 Archive](https://www.oracle.com/java/technologies/javase/jdk17-archive-downloads.html) (versions up to 17.0.12 are under the [NFTC](https://www.oracle.com/downloads/licenses/no-fee-license.html) license) and the [JDK 17.0.13+ Archive](https://www.oracle.com/java/technologies/javase/jdk17-0-13-later-archive-downloads.html) (versions 17.0.13 and later are under the [OTN](https://www.oracle.com/downloads/licenses/javase-license1.html) license). To stay on the free NFTC license, use `distribution: 'oracle'` with `java-version: '17.0.12'` (or earlier) instead of the floating `'17'`. Alternatively, upgrade to Oracle JDK 21+, which remains under the NFTC license.

+## Installing JDK without setting as default
+
+When installing multiple JDKs, the last one installed becomes the default (`JAVA_HOME`, `PATH`). Use the `set-default` option to install a JDK without overriding the default. The installed JDK is still discoverable via the `JAVA_HOME_<major>_<arch>` environment variable (e.g. `JAVA_HOME_21_X64`).
+
+```yaml
+steps:
+- uses: actions/checkout@v6
+- uses: actions/setup-java@v5
+  with:
+    distribution: 'temurin'
+    java-version: '17'
+- uses: actions/setup-java@v5
+  id: setup-java-21
+  with:
+    distribution: 'temurin'
+    java-version: '21'
+    set-default: false
+- run: |
+    echo "Default java:"
+    java -version
+    echo "Java 21 home: $JAVA_HOME_21_X64"
+    echo "Java 21 path from output: ${{ steps.setup-java-21.outputs.path }}"
+```
+
+In this example, `JAVA_HOME` and `java` on `PATH` point to Java 17, while Java 21 is available via `JAVA_HOME_21_X64` or the step output `path`.
+
+> **Note:** When a single step installs multiple JDKs via a multiline `java-version`, the `set-default` value applies to all of them. With `set-default: false`, none of those JDKs become the default; each remains discoverable through its `JAVA_HOME_<major>_<arch>` variable. Regardless of `set-default`, installed JDKs are still registered in the Maven toolchains file, so they can be selected via Maven toolchains.
+
 ## Installing Java from local file
 If your use-case requires a custom distribution or a version that is not provided by setup-java, you can download it manually and setup-java will take care of the installation and caching on the VM:
 
-> [!NOTE]
-> This approach also lets you use builds that setup-java does not provide directly, such as **Early Access (EA)** or other unreleased JDK builds (for example, an upcoming feature release or a Loom/Valhalla preview build). Download the desired archive in a prior step and point `jdkFile` at it; setup-java will extract, install, and cache it just like a supported distribution. When targeting multiple architectures, select the correct binary per architecture in your workflow (for example, with a build matrix).

-For example, to use an **Early Access** build from [jdk.java.net](https://jdk.java.net/), download the archive for your runner OS/architecture and install it via `distribution: 'jdkfile'` (example below assumes Linux x64):

 If your use-case requires a custom distribution (in the example, alpine-linux is used) or a version that is not provided by setup-java and you want to always install the latest version during runtime, then you can use the following code to auto-download the latest JDK, determine the semver needed for setup-java, and setup-java will take care of the installation and caching on the VM:
