Automated full e2e workflow hangs on PR changes

[MTrost]

When running the full e2e workflow on creating/changing a PR, the CI hangs up to the 60 minutes time limit for GH actions (see https://github.com/nuvla/ui/actions/runs/5003452734/jobs/8964696408).

In this issue I unblocked the pipeline by skipping some e2e tests (fix is in playwright.config.ts the grepInvert field): #1250

But skipping these tests is not necessary when running the e2e tests manually from the GH actions UI by providing the baseURI it should test against.

The changes between automatic and manual run:

• Automatic has one step that waits for Cloudflare preview deployment to finish. It sets the preview URL as a variable to later use as baseURI in the testing steps

• The manual run skips this step entirely

• Fix the hang up in CI
