bring smoke test suite over from veda-config

[stephenkilbourn]

This brings in the Playwright smoke test suite being used in veda-config. I thought that it would be helpful to have it here to assist in smoke testing after any updates.

• This is not tied to CICD at this time, so only runs locally with yarn test:e2e (although, that would be a straightforward follow-on)
• Tests are dynamically generated from the contents of the **/datasets/*.mdx' and*/stories/.mdx` directories to minimize maintenance of the suite
• tests aren't intended to be thorough on the UI, but rather to verify on a high level that there are no errors when loading routes or retrieving collections.
