feat: auto-detect Kubernetes crd schema

[qvalentin]

What does this PR do?

This PR adds an option to automatically detect the Kubernetes schema by parsing the contents of the document. In case a Kubernetes GroupVersionKind (GVK) is detected, the matching schema is retrieved from the CRD catalog.

What issues does this PR fix or reference?

#605

Is it tested? How?

Tests for parsing the Kubernetes Group Version Kind have been added

Updated version of #962 including the following changes:

• only run the auto-detect for files that are registered with the kubernetes schema
• check if the Kubernetes GroupVersionKind is already defined in the main kubernetes schema, if so, don't look it up in the CRD catalog
• add config option for crd catalog uri
• more tests

TODO:

• final testing
• add new options to readme

@qvalentin Thanks for the nice work. I actually started working on this as well: https://github.com/tricktron/yaml-language-server/tree/f-kubernetes-improvements

However, I just hardcoded the core kubernetes groups but yours looks better in my opinion. I then actually got sidetracked by adding some more features to my https://github.com/tricktron/crd2jsonschema tool so that I could easily test end-to-end with the newest openshift and tekton crds.

Maybe you can also take over some tests from my my branch, e.g. main...tricktron:yaml-language-server:f-kubernetes-improvements#diff-5d1a1b48130b3cb749d3ae36d72e52f8882d6fa5dc9eaedc5d6e606e411b176cR1194-R1219

And lastly, we should then probably add some documentation as well. This might be a breaking change for the helm language server where you hardcode the kubernetes schemas to templates/**. E.g. this is not needed anymore with this pr and I think it even results in some errors if I remember correctly from my e2e tests. Anyway, I won´t have much time to look at this until next Wednesday but still wanted to give you a fast feedback.

@tricktron I took a look at the schemaValidation.test.ts but since in my logic the customSchemaProvider has higher priority then the CRD logic the tests don't work with my branch.

But I might copy the config options format.
