There are no packages in Tor’s repositories for Wilma (see Index of /torproject.org/dists). Since Mint is either based on Debian or Ubuntu, I’d use the codename it is based on.
Since you are using Linux Mint 22 and not Linux Mint Debian Edition (LMDE 6), it should be based on Ubuntu 24.04, codename Noble.
However, Tor hasn’t released a version of little-t-tor (the Tor network daemon) for Ubuntu 24.04 yet. See Trouble adding tor repo to ubuntu noble (24.04 LTS) - #2 by capole.
