ci: Consider replacing `delete-artifact` with `cache` Action

[radeksimko]

Context

As part of adopting CRT, we also ended up adopting GitHub Action for deleting artifact https://github.com/marketplace/actions/delete-artifact

Ideally CRT would allow us to filter which artifacts we want to upload, which is a planned feature.

That said, in practice we may not need to make provider schemas an actual artifact. We may be able just treat it as a cache entry and use the actions/cache/save and actions/cache/restore instead.

Terraform faces similar problem and uses the actions/cache Action:
https://github.com/hashicorp/terraform/blob/main/.github/workflows/build.yml#L155-L254

Proposal

Investigate replacing upload-artifact, download-artifact and delete-artifact with actions/cache:
