Fix rendering of settings by adding ids to package.json

This appears to fix a problem I noticed, where all the settings defined
by this extension appeared in the settings UI under "Extensions->CLI"
(the name of our first config category), rather than
"Extensions->CodeQL->CLI", "Extensions->CodeQL->Running queries", etc.
