Submit the public key for Provider signing to OpenTofu

[mpepping]

Using the gavinbunney/kubectl provider with OpenTofu shows a warning on Signature validation:

Installed gavinbunney/kubectl v1.14.0. Signature validation was skipped due to the registry not containing GPG keys for this provider

There's a "Submit new Provider Signing Key" issue template on the OpenTofu registry project to make submitting GPG public keys easy:

https://github.com/opentofu/registry/issues/new/choose

Would you please take a moment to submit the public signing key to the OpenTofu project, so that tofu users can install the gavinbunney/kubectl provider without any warnings?

@gavinbunney, can you look into this? Low effort, but actually fixing this comes down to you.

I also would like you to look into this. It caused a whole mess of problems with our setup.

Just fiy, this provider is long abandoned and causing issues on newer versions of kubernetes. There is a fork I am maintaining (with some new features) at https://registry.terraform.io/providers/alekc/kubectl/latest/docs
