feat: add .mvn/extensions.xml to Maven cache key pattern

Closes #990

Maven build extensions declared in `.mvn/extensions.xml` can introduce
additional plugin dependencies (e.g. lifecycle participants, custom
packaging types). Including this file in the cache key hash ensures that
changes to extensions — which affect what plugin JARs Maven downloads —
properly invalidate the cache, preventing stale caches from missing
newly-required plugin dependencies.

Changes:
- src/cache.ts: add `**/.mvn/extensions.xml` to Maven pattern array
- __tests__/cache.test.ts: update pattern expectations; add new test
- README.md: document the new file in the Maven cache key hash list

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.
