[ulucinar]

Reverts #238

Turns out that the generators for the AWS provider:

❯ git status apis
On branch bump-upjet
Your branch is up to date with 'origin/bump-upjet'.

Changes not staged for commit:
  (use "git add <file>..." to update what will be committed)
  (use "git restore <file>..." to discard changes in working directory)
        modified:   apis/lightsail/v1beta1/zz_bucket_types.go

no changes added to commit (use "git add" and/or "git commit -a")

For provider-gcp:

❯ git status apis
On branch bump-upjet
Changes not staged for commit:
  (use "git add <file>..." to update what will be committed)
  (use "git restore <file>..." to discard changes in working directory)
        modified:   apis/cloudplatform/v1beta1/zz_serviceaccount_types.go

        modified:   apis/kms/v1beta1/zz_keyring_types.go
        modified:   apis/kms/v1beta1/zz_keyringimportjob_types.go

no changes added to commit (use "git add" and/or "git commit -a")

I did not check provider-{azure,azuread}.
