docs(changelog): categorize scopes

This change makes a best-effort attempt to categorize the various
Conventional Commits scopes that have been used over the past year into
their relevant changelog sections. No scopes were formalized for the
v2.5 release so it varies dramatically, but the output does not look
totally awful. Nonetheless, it will need some manual tweaking.

For every section with one or more potential scopes, the first scope
represents the "blessed" scope. That is, the scope that new commits that
belong to this category should use.
