Merge 18d114c65a into fe779bf55e

Updated the Java version in the README setup examples from 21 to 25
to reflect the latest supported version. This change ensures that
users are guided to use the most current Java version for their
projects.

- Updated all instances of 'java-version: 21' to 'java-version: 25'
- Modified supported version syntax to include '25'

 #### Cache segment restore timeout
 Usually, cache gets downloaded in multiple segments of fixed sizes. Sometimes, a segment download gets stuck, which causes the workflow job to be stuck. The cache segment download timeout [was introduced](https://github.com/actions/toolkit/tree/main/packages/cache#cache-segment-restore-timeout) to solve this issue as it allows the segment download to get aborted and hence allows the job to proceed with a cache miss. The default value of the cache segment download timeout is set to 10 minutes and can be customized by specifying an environment variable named `SEGMENT_DOWNLOAD_TIMEOUT_MINS` with a timeout value in minutes.
