This introduces tooling and enforcement for formatting bazel files.
The tooling is provided as a bazel run target from
[keith/buildifier-prebuilt](https://github.com/keith/buildifier-prebuilt).
This is used in a [`pre-commit`](https://pre-commit.com/) hook for those
having that installed. In turn this is used in a CI check. Relying on a
`pre-commit` action gives us easy checking that buildifying did not
change anything in the files and printing the diff, without having to
hand-roll the check ourselves.
This enforcement will make usage of gazelle easier, as gazelle itself
might reformat files, even outside of `go`. Having them properly
formatted will allow gazelle to leave them unchanged, without needing
to configure awkward exclude directives.
This commit modifies the check for the "py" launcher on windows. We now look for the launcher only if the python_executable_name extractor option is not specified.
These failures were likely caused by
https://github.com/github/codeql/pull/16127
My guess is that they can probably be deleted altogether, but as the
failures are blocking other development, I have opted to simply disable
them for the time being.
Two issues:
- Tests relying on existing query machinery (i.e. `import python`) were not resolving
correctly due to a bad `qlpack.yml` file.
- The diagnostics output tests needed an updated import to account for their new location.
