ci(buildkite): exclude files/folders that are not tested in Buildkite

[v1v]

Proposed commit message

Skip files that are not used in Buildkite
Run faster builds and avoid waste of CI cycles.

I decided to support the whole .github folder since there are some other files, such as CODEOWNERS or .dependabot.yml and the rest are not used by Buildkite
