The SDK proto check and sync dashboard jobs pinned the CI container to
image tag 37072ee8, which predates several mise.lock updates. Tools
baked into that image no longer satisfied the lockfile, so every run
re-downloaded go and yq from the GitHub release CDN and failed whenever
that CDN returned a transient error.
Repin to 5b9daab9, the current CI image build, so mise install resolves
entirely from the baked toolchain. The pin stays an explicit tag to keep
the zizmor unpinned-images rule satisfied.
