Document Bazel build support in the User Guide

[NikhilGupta-Dev]

Added a documentation section referencing the official JUnit 5 + Bazel starter project.

This PR adds Bazel build support documentation to the running-tests.adoc file. The new section provides users with information about Bazel's support for running tests on the JUnit Platform and includes a reference to the official JUnit 5 + Bazel Starter Sample project.

Related to documentation improvement efforts for better build tool coverage.

Hi @NikhilGupta-Dev,

I'm not sure if this is a "work in progress", but you deleted large sections of the documentation.

Please undo that and submit only changes that introduce documentation for Bazel.

Thanks

Hi @sbrannen, I have restored the original documentation and added the Bazel section exactly as requested. No other content was changed. Thank you for your guidance—please let me know if there is anything further needed.

Ho @NikhilGupta-Dev

did you create the modified User-Guide on your machine and verified the existing hierarchy didn't change?

I think, they are off by more then one.

Are you sure you want to add the Bazel-related texts into an IDE-related section?

No. Please move them to https://docs.junit.org/current/user-guide/#running-tests-build - right next after the Ant section.

Also, please revert the deletion of empty lines your commit shows here: https://github.com/junit-team/junit-framework/pull/4883/files

In addition to that, it suffices to write "JUnit" instead of "JUnit 5" - as number 6 is just around the corner.
