Release Posts to Docs
## Summary
Move [release posts](https://about.gitlab.com/releases/categories/releases/) (monthly and patch) to the docs site
## Why
Eliminate repetition and churn that comes from wrangling epics/issues into public facing assets. We want to go from [3 separate lanes of work](https://docs.google.com/presentation/d/1eA19AMVt-CEvBtD0loHwaY1-6gZJjPiK0eXfjjg1o0M/edit?slide=id.g3d0e0ade90a_0_0#slide=id.g3d0e0ade90a_0_0) to [one lane of effort](https://docs.google.com/presentation/d/1eA19AMVt-CEvBtD0loHwaY1-6gZJjPiK0eXfjjg1o0M/edit?slide=id.g3d0e0ade90a_0_53#slide=id.g3d0e0ade90a_0_53).
It turns the release post into release notes, with a more targeted focus.
From [communicating releases doc](https://docs.google.com/document/d/1q_lj2gNY-3QmUc5ZNZC5KKS_iwp09_0J_tRUocgqdNw/edit):
> Make Docs the canonical technical source of truth and use curated product blogs for thematic stories [so that there are] only two sources of truth for launches, blogs for "why" and "what" and docs for "technical how."
Additionally, it will decrease complexity of the process, eliminate the release post manager role, and decommission unmaintained code.
Note: Deprecating the existing release post process was [one of the options presented in the most recent review](https://gitlab.com/gitlab-com/Product/-/work_items/14295).
