Feature request: Schema validation for catalog-info

[ehrnst]

Hi.

Any plans to introduce schema validation to catalog-info files? I think it would be a great addition :)
Schema for backstage can be found here https://json.schemastore.org/catalog-info.json / https://github.com/backstage/backstage/blob/master/packages/catalog-model/src/schema/Entity.schema.json

The YAML extension by RedHat already does this automatically.

Maybe we should recommend it in the readme, or add it to extensionDependencies in the manifest?

I added the schema to my YAML validation in vsCode. It just seems a bit redundant when this plugin exists already :)

I might be mistaken, but it appears that vscode does not inherently provide support for json-schemas with yaml files. To enable YAML validation, a language server needs to be implemented with json schema integration. As @h3rmanj mentioned, RedHat's YAML language support, which is considered the de-facto standard, already has this feature implemented.

With this in mind, I believe that incorporating validation functionality is beyond the scope of the Backstage plugin. I'd rather modify the package.json manifest to include redhat.vscode-yaml as an extensionDependency.

@ehrnst any tips on how to provide this functionality without re-inventing the wheel would be greatly appreciated.
