Setup e2e workflow

[mendaomn]

Description

This PR adds a GitHub Action workflow to run e2e tests with Playwright. The included test is just a sample

Changes

• add manually triggered workflow to run e2e tests with playwright
• add e2e:test script to run tests locally as well
• configure playwright to record video and trace in case of failure
• configure workflow to store such video and trace in the run artifact

How Has This Been Tested?

• by running the workflow on the branch, see run here
• Please note: the sample test runs against an ephemeral environment, real tests should refer to our demo environment

References

• Previously an investigation had been carried over here

PR Quality Checklist

• [ ] I added tests to new or existing code
• [ ] I removed hardcoded strings and used our i18n solution instead (see here)
• [ ] I made sure no sensitive info gets logged at any time in the codebase (see here) (e.g. no user info or details, no stacktraces, etc.)
• [ ] I checked that infrastructure/update_infrastructure.sh runs without any error
• [ ] I checked that npm run build builds without any error
• [ ] I checked that clusters are listed correctly
• [ ] I checked that a new cluster can be created (config is produced and dry run passes)
• [ ] I checked that login and logout work as expected
