[#2252] Enable CI Checks on PRs and Restrict Deployment to Master

[JoanneHing]

Part of #18 in Reposense Repository

Proposed commit message

Run checks on PRs and deploy only on master push

This PR updates the CI workflow to ensure that Install dependencies
and Generate report run on all PRs, while deployment to GitHub Pages
happens only on pushes to the master branch. This change ensures
that pull requests are properly tested before merging, preventing
unintended deployments from feature branches and improving 
CI reliability.

Sorry didn't realized that the text wrapper I used wasn't functioning correctly. Fixed!
