Make aliases of `database` option in generators work

Thor automatically adds `-` if aliases do not start with `-`.
https://github.com/erikhuda/thor/blob/0879c1773d188902d54f95174f33961ac33111f8/lib/thor/parser/options.rb#L53

But Thor follows a convention of one-dash-one-letter options.
So, even if `-` is added to `db`, it does not work.

Follow up #34021.
