Check if there are incorrect submission directories

[Matistjati]

For each directory in submissions:

• If it exactly matches some directory from the current problem version, do nothing
• Otherwise, if it almost matches, warn for a potential typo
• Otherwise, check if it matches some other directory from another format version

Sample output:

WARNING Potential typo: directory submissions/partially_acceptedd is similar to partially_accepted
WARNING Directory submissions/brute_force is not part of format version legacy, but part of 2023-07-draft

The magic value 0.75 was chosen quite arbitrarily.

Not fixing the codefactor error, the TODO is pretty much impossible to fix currently.
