The previous approach (migration script) was flawed: _skip_if_exists
causes copier to re-create the file on every subsequent upgrade, so
the migration would remove it only for it to come straight back.

The correct fix is removing docs/ARCHITECTURE.md from _skip_if_exists
entirely. With copier's 3-way merge, downstream projects can delete
the file with a git commit and future upgrades will respect that
deletion. If we later decide to remove the file from the template, it
will propagate to all downstream projects automatically.
