Testing Bazel 9.0.0rc5 by updating .bazelversion and MODULE.bazel.lock.

Code Review

This pull request updates the Bazel version to 9.0.0rc5 and regenerates the MODULE.bazel.lock file. The changes, including the updated lockFileVersion and the new format for module extensions within the lock file, are consistent with the Bazel version upgrade. The changes appear correct for the stated purpose of testing the new Bazel release candidate.

I'm seeing a lot for errors like:

/cc @coeuvre Do we need to upgrade the config again?

[fmeum]

@meteorcloudy Turns out the remote repo contents cache is always used for writes, even if not enabled. I'll send a fix for that and also to avoid the warning spam.

@fmeum Awesome, thanks!

@iancha1992 @Wyverald Looks like we'll need another quick rc.
