docs: add FAST to showcase

[Josh-Cena]

Pre-flight checklist

• I have read the Contributing Guidelines on pull requests.
• If this is a code change: I have written unit tests and/or added dogfooding pages to fully verify the new behavior.
• If this is a new API or substantial change: the PR has an accompanying issue (closes #0000) and the maintainers have approved on my working plan.

Motivation

Close #7099

@huynhicode @EisenbergEffect Would be great if you can give an approval. Otherwise I'm going to merge this on Friday anyways.
