Fix (get-info :authors) (#7373)

This PR fixes calling (get-info :authors). It used to (try to) print the whole about() information, but failed to do so because the string needed to be turned into an s-expression. However, about() is not properly escaped.
We now simply print the cvc5 authors.
It also fixes isValidGetInfoFlag() which was missing filename.

Fixes #7362.
