[bazel] Replace git_repository with http_archive. (#99422)
The current git_repository usage points to tags, which leads to warnings
that the build may not be reproducable due to not using a git sha.
The docs for
[git_repository](https://bazel.build/rules/lib/repo/git#git_repository)
recommend using `http_archive`, so switch to that instead. Also bump to
newer versions for these two repos.
