Migration of Common_gc tests from Robot to Playwright

[adityachopra29]

Comprehensive Summary of your change

• This PR implements the complete migration of the Common_GC.robot robot test suite to Playwright.

• This PR builds upon the existing PR for playwright setup feat: Add Playwright setup #22462.

Changes Made

• Created a file common-gc-spec.ts containing all the tests.
• Since most of the tests in this suite relied heavily on resource functions present in tests/resources, all necessary ones have been implemented.
  - They include setup, cleanup and navigation functions
  - Helper functions for pulling, pushing, tagging etc. images to a project
• All tests are independent and self-contained.
• Integration with the existing Playwright configuration and GitHub Actions workflow.

Issue being fixed

To the maintainers @bupd @Vad1mo @wy65701436 @OrlinVasilev. This pr is ready for review. Please take a look.

One thing to note here is that the tests Garbage Collection and Garbage Collection Accessory are check the working of the GC in different senarios, but GC does not consider artifacts uploaded in the past 2 hours, so it does not consider the project and artifacts that we push for testing.
Any suggestions on how to handle this?

Also, I found that there are a lot of different utility functions (for cosign/notation operations, docker functions, harbor navigation, etc) that I found will be used by other test cases as well, and everybody is reimplementing them for now...so I guess we need to modularize this at some point in time...so we should probably have an approach for this as well.
For now I have included them all in one file, but I can separate that out once the plan is decided. What do you suggest?

[adityachopra29]

Lastly, currently, we don’t have a good developer setup for building Playwright tests. The playwright.yml file can’t be used to create a dev environment, which made local development inefficient for me. I’ve added a temporary workaround using sample.env, but a Docker-based setup similar to the Robot test cases would be a better long-term solution.

So currently the dev workflow is simple you just need to npm install which would install playwright

And for running playwright use npx playwright

On the sample env part and the playwright.yml this might be a good addition given that it simplifies the env required to run playwright tests locally

You can check the proposal i have linked the dockerfile for running playwright.

Okay..found the docker file
