x/pkgsite: package removal request for github.com/dalet-oss/{terraform-provider-kowabunga,kowabunga-api}

[gxben]

Can you get rid of the following packages ?

• https://pkg.go.dev/github.com/dalet-oss/terraform-provider-kowabunga
• https://pkg.go.dev/github.com/dalet-oss/kowabunga-api/sdk/go

They've moved to another location now and their respective upstream GitHub repository have been removed.

Thanks,

We'll also need you to demonstrate some sort of ownership association with the repos in question, such as publicly viewable membership in the owning organization
