Add remaining ToCs to ToC lint (pytorch#56487)

Summary:
The lint was originally added in pytorch#54974, but at the time I didn't realize that these other Markdown files also each have a table of contents:

- `GLOSSARY.md`
- `torch/csrc/jit/OVERVIEW.md`
- `torch/csrc/jit/docs/serialization.md`
- `torch/fx/OVERVIEW.md`

This PR adds those files to the lint, and also changes the rule from using a fixed list of filenames to a `git grep` command that finds all Markdown files containing this magic comment:

```md

```

Pull Request resolved: pytorch#56487

Test Plan: The "Lint / toc" job in GitHub Actions.
