Fix the package listing and the repository links

Three things, all of them stale rather than newly broken.

**The README listed seven of the ten packages.** `dastdown`,
`slate-utils` and `generic-html-renderer` were never added when they
appeared, so the monorepo's own front page under-reported itself by
three. (`to-markdown` was already there.)

**Every link pointed at a `master` branch this repository does not
have.** The default branch is `main`; `master` resolves only because
GitHub still redirects the old default branch name, which is not
something to keep depending on. 10 links in the README and the
`homepage` of all ten manifests.

**Two of those homepages were a genuine 404**, redirect or not:
`datocms-structured-text-utils` pointed at `packages/datocms-structured-text-utils`
and `datocms-structured-text-slate-utils` at
`packages/datocms-structured-text-slate-utils`, neither of which exists —
the directories are `packages/utils` and `packages/slate-utils`. `homepage`
is what npm renders on a package's page, so those were dead links on two
published packages, one of them the most depended-on in the repo.

Verified: all ten now return HTTP 200 directly, with no redirect.

Also deletes `packages/to-markdown/REVIEW.md`, 2787 lines of one-off
review notes committed by accident alongside the package itself. It is
dated 2025-10-01, reviews version 5.1.4, and its headline is "Block
release until P0 items are fixed" — for a package that has since been
released and is now at 6.0.0. Checked before deleting that the P0 it
blocks on is gone: it warned that `render()` kept list state at module
level and was therefore unsafe under `Promise.all`. There is no
module-scope mutable state in the source any more, and rendering three
documents concurrently now produces output identical to rendering them
in sequence. The file is not in `files`, so it was never published.

No changeset: nothing here changes behaviour, and the manifest links
reach npm with each package's next release.
