Contributor Instructions for Adding Resources to This Provider

[daviddyball]

What problem are you facing?

I'd love to contribute to this provider, but I can't find any instructions on adding a new resource (e.g. SchemaRegistrySubject)

How could Crossplane help solve your problem?

Update README.md or add CONTRIBUTING.md to the repo with some additional guidance on extending the provider, or a link to instructions on extending providers.

Hey @daviddyball, have you checked out the Upjet documentation?

https://github.com/crossplane/upjet/blob/main/docs/README.md#generating-a-crossplane-provider-using-upjet
https://github.com/crossplane/upjet/blob/main/docs/configuring-a-resource.md

Excellent. That's most helpful @jaylevin . I will start going through that.

Would it be worth adding it to the README.md for future travellers?
