Allow bot triggered PRs to run CI

[dliappis]

This commit allows Buildkite run CI for bots generated by the dependabot and mergify bots, thus removing the need to manually allow execution with the trigger phrase.

I will merge this now, despite the CI check failing with

# golang.org/x/tools/go/types/objectpath
/go/src/golang.org/x/tools/go/types/objectpath/objectpath.go:397:10: meth.Origin undefined (type *types.Func has no field or method Origin)
Error: running "go get golang.org/x/lint/golint" failed with exit code 2
🚨 Error: The command exited with status 2
user command error: exit status 2

because the underlying problem was already present, isn't related to this PR, and should be addressed in a follow up PR.
