Subject: [PATCH] Use CI_ACCESS_TOKEN to create release PR (#5286)

## Problem

If @github-actions creates release PR, the CI pipeline is not triggered
(but we have `release-notify.yml` workflow that we expect to run on this
event).
I suspect this happened because @github-actions is not a repository
member.

Ref
https://github.com/neondatabase/neon/pull/5283#issuecomment-1715209291

## Summary of changes
- Use `CI_ACCESS_TOKEN` to create a PR
- Use `gh` instead of `thomaseizinger/create-pull-request`
- Restrict permissions for GITHUB_TOKEN to `contents: write` only
(required for `git push`)
