search: Update supported languages in lang: filter suggestions
Created by: fkling
Fixes https://github.com/sourcegraph/sourcegraph/issues/32579
I updated the list by running the command in the comment.
What surprises me: JSX was removed and is indeed not supported (see
issue) but other removed entries, e.g. EML still seem to be supported
by the backend.
Test plan
Searched for files matching some of the newly added languages.
