Remove remnants from "LSIF Typed" (#191)

* Remove remnants from "LSIF Typed"

The codebase had a lot of outdated references to "LSIF Typed", which has
been renamed to SCIP. This commit replaces these outdated references to
avoid confusion for people who are reading the codebase for the first
time.

* Empty commit to trigger ci
