docs: tighten two lines from the #2 review

[adrianbrowning]

Follow-up to #49, which merged before this commit was pushed.

Summary

 README.md (quick start)
-CI runs the same two steps in the same order, with `--check` instead of `--apply`:
+In CI, run the same two steps in the same order, with `--check` instead of `--apply`:
 packages/mdcode/README.md (mdcode and Snippet Checkers)
-mdcode can also run your own type checker over blocks written in the Markdown. [`validate-snippets.mjs`] extracts ...
+For blocks written in the Markdown, the ready-to-copy [`validate-snippets.mjs`] script can run your own type checker. It extracts ... with `mdcode extract` ...

The first line was worded as a fact about CI. It's a recommendation. The second gives the credit to the copyable script: mdcode itself only extracts the blocks, and the script runs the checker (Validating Runnable Snippets in CI, step 2).

Evidence

The pre-push pnpm check passes.

Merge Danger

Door: two-way

Blast Radius: docs

[github-actions]

This PR changes 1 package but has no bump file, so this check is failing.

Changed package(s) without a bump file:

• mdcode-ts

If these changes should be released, add a bump file describing the version bump. If no release is needed (e.g. a dependency-only or dev-only change), add an empty bump file to acknowledge that intent — that satisfies this check without bumping any package.

pnpm exec bumpy add            # describe a release
pnpm exec bumpy add --empty    # acknowledge no release is needed

Or directly on GitHub: add a bump file · add an empty bump file.
