build: reorder workspace patterns for changelog CI compatibility

The changelog-check script in github-tools iterates workspace patterns
in order and returns the first match. With "packages/*" listed first,
files under packages/snaps/simple-keyring/ resolve to the phantom
"packages/snaps" package (which has no package.json), causing the CI
check to fail.

Listing more specific patterns first ensures files under
packages/snaps/ correctly resolve to their actual package, which is
marked private and is therefore skipped by the changelog check.
