feat(corp/data-import): build morphology database in derivation r/5693

This makes the actual imported database of the ~whole Russian
language (all lemmas, grammemes, forms etc.) a Nix build target which
is built in CI.

This still needs schema normalisation (it's fairly directly mapped to
the raw data), but it's already starting to be a useful data set.

This also happens to be a pretty cool demonstration of the power of
Nix. You can do `nix-build -A corp.russian.data-import.database` and
out comes a perfectly valid SQLite database with a valid external data
import!
