chore: check in types

To ensure that changes to code/types doesn't result in unwanted changes in type generation, or that bumps to dts-buddy don't cause unwanted regressions, we're checking in the generated types. Types should be committed as-is (don't format it with prettier!). CI is enhanced to check that git sees no changed files after generating the types, which would mean types have changed.
