Remove redundant github.repository check from both jobs

The `pull_request_target` trigger always runs in the context of the
base repo, so `github.repository` is always `integrations/terraform-provider-github`
for PRs opened against this repo. For issues, the workflow only fires
on the repo's own issue tracker. The check adds no value in either case.

Addresses review feedback from @stevehipwell.
