fix(prover_cli): Remove congif file check (#2695)

This is a temporary fix to allow the CLI binary to be used directly
without having the repository cloned.

Note: The 'config' command does not work when used this way, and you are
required to specify the database URL each time you use the CLI, as the
config does not persist.

A more reliable solution is being worked on, but in the meantime, it was
necessary to use it this way.
