Enable GitHub actions preview workflow (#7)

This PR makes the following changes
1. Allow `build-deploy` workflow to run when commits are pushed (preview
is enabled so changes from PR are deployed to a draft)
2. Add linting to ci
3. Make a one character change to oidc.yaml to trigger workflow for
testing results
