chore(test): adding playwright e2e test

[danivilla9]

Fixes issue #313. This PR introduces E2E tests using Playwright

In order to test:
1-Clone the podman-desktop repository
2-Go to podman-desktop folder
3-Execute pnpm install
4-Execute pnpm test:e2e:build
6-Set environment variable executing: export PODMAN_DESKTOP_ARGS="/path/to/podman-desktop"
7-Go to crc-extension folder
8-Execute yarn install
8-Execute yarn test:e2e

*Remember that you have to use the latest version of @podman-desktop/tests-playwright in order to execute the tests

Works for me, but I leave the approval to @odockal.

Description for the PR should be updated:

1. (2,3,4) should be updates to call pnpm from root of the podman-desktop
2. use yarn for the extension, because it is not migrated to pnpm yet.

Can't test it on Windows and seems yarn install and yarn test:e2e are enough at the root of the repo

@danivilla9 Can you please try also run the tests on the windows? you can use this workflow: https://github.com/containers/podman-desktop-e2e/actions/workflows/desktop-e2e-test-job-windows.yaml.

We found out after discussion that we also need to add a test for a crc-extension dependency - Red Hat Authentication. So to check the presence of RH SSO once the OpenShift Local is installed and its state should be part of e2e tests.

We also encountered a bug. Which will be reported. We might consider to eventually add a test to cover this bug in another issue. @danivilla9 ^^
