Bazel 8.0 LTS just got released: https://github.com/bazelbuild/bazel/releases/tag/8.0.0
However, we're still running on 6.5.0: https://github.com/p4lang/p4runtime/blob/a41e728e14682d3e3c651057a526edfed7b27a6f/bazel/example/.bazelversion

This issue tracks upgrading to Bazel 8 to fight bit rot.

I also opened a related issue tracking upgrading from WORSKPACE files to Bzlmod, since the latter are deprecated in Bazel 8: #515
