chore(tools/cheddar): bump to syntect 5.0 r/5622
Upgrade to syntect 5.0 and load the new kind of syntax set
serialisation with the new helper function for that purpose.

Includes other minor API fixes as well, note that the things that are
now calling `expect` previously failed internally at those points and
we're reasonably confident they don't fail in production.

This has been waiting for a long time ...
