Move fs-extra back to dependencies

I moved it to devDeps by mistake in #1272 , didn't see it was imported as 'fs-extra/esm' in a command.

We detected some changes in packages/*/package.json or packages/*/src, and there are no updates in the .changeset.
If the changes are user-facing and should cause a version bump, run npm run changeset add to track your changes and include them in the next release CHANGELOG.
If you are making simple updates to examples or documentation, you do not need to add a changeset.
