chore(release): Fix hang in the test suite

[jamesdaniels]

Github Actions was a bit flaky last night, so I YOLO'd the tag... I had a real flake. This is why you don't try to push something out at 4am. I was just a test but it could've been a production issue.

• Check for file existence before npm install on deploy, this was hanging up in some test environments
• Prefer absolute paths on the deploy pipeline
• Fix ng add stalling if you don't select any options
