actions: update github workflows to use go1.18 (#34897)

We haven't yet upgraded to 1.18 on buildkite. However, we should be able
to update in github actions. There shouldn't be any issues around these
being out of sync, and this reduces the amount that changes in one go
when we move asdf to 1.18.

  fastmod --hidden '(go-version.*)(\b1\.17\b)' '${1}1.18'

Test Plan: CI is green
