Provide linting for ansible-builder files

[tima]

SUMMARY

Customers should be able to run linting against a builder file. 

This would include syntax and package dependency errors. If we could provide simple steps on how to resolve any dep conflicts within that builder file it would provide some relief for customers who are not python developers trying to use builder for EEs.

@tima Can you please be more specific and also include links to documentation. What do you mean by "ansible-builder files"? Is that the definition of an execution environment, because for these we are already having a JSON Schema that we use to check against, see https://github.com/ansible/ansible-lint/blob/main/src/ansiblelint/schemas/execution-environment.json -- Are there other files?

Now the bad part about it is that the JSON Schema should have being maintained by ansible-builder project itself and not the linter. For example the rule-books JSON schema is maintained by the team developing them, and the linter is only caching it and automatically updating the schema when needed.

Checking conflicts on dependencies is unlikely to be doable in linter as it would require effective build. Still, other stuff might be possible but we will need specific proposal for implementing them.

@cidrblock WDYT?
