Update GitHub Actions workflows. (#2345)

This PR was triggered by @t0yv0 generated by the
update-workflows-ecosystem-providers workflow in the pulumi/ci-mgmt
repo, from commit
[4a5248b08f62e1bd9e1afbd5df812ead07903d3f](pulumi/ci-mgmt@4a5248b).

## Rebasing this PR

If this PR falls behind `master` on pulumi-eks and needs to be
regenerated against the latest tip, dispatch
[`update-workflows-single-bridged-provider`](https://github.com/pulumi/ci-mgmt/actions/workflows/update-workflows-single-bridged-provider.yml):

```sh
gh workflow run update-workflows-single-bridged-provider.yml \
  --repo pulumi/ci-mgmt \
  -f provider_name=eks \
  -f automerge=false
```

That re-runs this same workflow against current ci-mgmt `master`, closes
this stale PR (via the "obsolete PR" cleanup step above), and opens a
fresh one rebased on the provider's current `master`.
