Wrong path being used for idb_companion

[kmarple1]

Description

I have installed idb_companion per the documentation. which idb_companion returns "/opt/homebrew/bin/idb_companion". However, I keep seeing this error in Flipper (full log entry below): "FileNotFoundError: [Errno 2] No such file or directory: '/usr/local/bin/idb_companion'".

See #851

However, that may will not get merged because I'm not willing to try to get my employer to sign the CLA.

Perhaps someone who does have a CLA might be willing to duplicate the change in the PR into their own PR.

[heath-clink]

this appears to work as a workaround:

sudo ln -s /opt/homebrew/bin/idb_companion /usr/local/bin
