github/workflows/provider-prerequisites.yaml's Comment on PR with Details of Schema Check breaks fork based PRs

[denopink]

Looks like the sub-job Comment on PR with Details of Schema Check requires the workflow's github.token to have read and write permissions.

This becomes an issue when a pr is created from a fork, since the token is from the fork and not from the parent repo.

Can we remove this section?
