package/release: Add github-verify-release job (#10476)

### Describe Your Changes

The job ensure that:
- the draft release with given `$(TAG)` exists
- the release has excpected `$(GITHUB_ASSETS_COUNT)` number of uploaded
assets
- All the assets were uploaded succesfully.

It also adds helper job `github-get-release` which finds a draft release
by `$(TAG)` and stores into file `/tmp/vm-github-release-$(TAG)` file.

The `github-delete-release1 job is decoupled from the file produced by
`github-create-release job`. So it could be run at any time from any
machine.
