chore(deps-dev): switch license-checker package (#262)

`license-checker`, which we use for enforcing rules around allowed
dependency licenses, appears to be no longer maintained and leads to
various deprecation warnings when installing it. This commit changes the
installed package to `license-checker-rseidelsohn`, which seems to be
the most up-to-date and actively maintained fork.
