1. Sets src/cryostat-web git submodule as a Yarn workspace
2. Deduplicates the plugin's own package.json to remove dependencies which are really use by cryostat-web and not by the plugin itself
3. Downgrades a few versions to match what's provided by the target OpenShift Console version

Content looks good! Although there's some issues at the moment.

I opened a PR to update the Cypress tests as they might be useful here to just check that everything opens as expected: #909

Thanks @aptmac , the CI failures were because the cryostatio/cryostat-web#2222 changes weren't included. I've added the submodule update in here now (again) and it looks like it should pass this time.
