fix: add pull_request trigger to CI workflow so tests gate all PRs

The CI workflow previously only triggered on push to master, meaning PRs
were not tested before merge. Add pull_request trigger for the test job
while restricting the Docker build+push job to push events only.

Closes leeworks-agents/gitea-mobile#204
