endpoint update: /validate to /$validate

According to the validate operation definition the URL should be of the form URL: [base]/[Resource]/$validate and the operation cannot be run at the system level according to the spec. The most basic solution here could be a wildcard, which would work well enough for us because inferno-core and any other client could call with a valid Resource name and get a result. I'd start with this.

Also, I didn't mention this before, but I think we should add this new route alongside the existing route to ease our upgrade client upgrade path (i.e. we could merge this without needing a complementary inferno-core upgrade). Otherwise if we merge this and push a new dockerhub image and deploy inferno-core would break because it's not using the new route.

Side Note:
If we can get that working then we might be able to do something fancier where we get a list of children (maybe with Resource#listChildren?).

Can you adjust the output of the tests? Currently it prints to STANDARD_OUT, while the other tests in the repo return a value of PASSED, SKIPPED, or FAILED. Let's get it to match the rest of the repo. It's worth looking at the Github actions failures messages to see what I'm talking about (the red X marks at the bottom of the PR conversation tab).

Can you rebase against main?
