Map Zulu x86 architecture to i686 for Azul Metadata API (#1079)

The Azul Metadata API's `arch=x86` returns both 32-bit (i686) and 64-bit
(x64) packages. Because the two variants share identical java_version and
distro_version, setup-java cannot distinguish them and may resolve an
explicit `architecture: x86` request to a 64-bit JDK (and for Java 21+,
where 32-bit is dropped, x86 silently returns x64 instead of failing).

The legacy Zulu Discovery API used `arch=x86&hw_bitness=32` to target only
32-bit builds. The Metadata API exposes the equivalent via `arch=i686`,
which returns only genuine 32-bit builds with full version parity to the
old behavior. Map x86 -> i686 to restore correct 32-bit resolution.

 The action has a built-in functionality for caching and restoring dependencies. It uses [toolkit/cache](https://github.com/actions/toolkit/tree/main/packages/cache) under hood for caching dependencies but requires less configuration settings. Supported package managers are gradle, maven and sbt. The format of the used cache key is `setup-java-${{ platform }}-${{ packageManager }}-${{ fileHash }}`, where the hash is based on the following files:
 
 - gradle: `**/*.gradle*`, `**/gradle-wrapper.properties`, `buildSrc/**/Versions.kt`, `buildSrc/**/Dependencies.kt`, `gradle/*.versions.toml`, and `**/versions.properties`
-- maven: `**/pom.xml` and `**/.mvn/wrapper/maven-wrapper.properties`
+- maven: `**/pom.xml`, `**/.mvn/wrapper/maven-wrapper.properties`, and `**/.mvn/extensions.xml`
 - sbt: all sbt build definition files `**/*.sbt`, `**/project/build.properties`, `**/project/**.scala`, `**/project/**.sbt`
 
 When the option `cache-dependency-path` is specified, the hash is based on the matching file. This option supports wildcards and a list of file names, and is especially useful for monorepos.
