Request review criteria:

Self checklist (all need to be checked):

• Testing instructions have been added in the PR body (for PRs involving changes that are not immediately obvious).
• The developer has added tests or explained why testing cannot be added (unit tests & storybook for related changes)

If you have UI changes:

• Included any necessary screenshots or gifs if it was a UI change.
• Included tags to the UX team if it was a UI/UX change (find relevant UX in the SMEs section).

@christianvogt Some more suggestions.

1. Can you pls update the architecture of e2e testing here

2. In the /src/__tests__/e2e folder, there is currently a test named CreateEditDeleteProject.spec.ts written in Playwright. Could we consider removing this folder, because that is already migrated to cypress in this PR?

[christianvogt]

@dpanshug I'm going to update docs in another PR. This was just an initial delivery to get started. I even have more work right now that builds on this PR and changes up more things.

I am not removing playwright tests as part of this PR either because there's more work to be done to get parity. That will come later.

[christianvogt]

added a 2nd commit that builds on the first and migrates the playwright tests to cypress
