Show forc plugin path warning only in verbose mode

[sdankel]

Description

This warning is mostly unnecessary. For fuelup users, it's expected that they might install some forc plugins outside of fuelup (with rust, nix, npm, etc.). For pure nix users, the paths will always be different, for example:

warning: The fmt (/nix/store/hwd7z0zyfvk331vfiqg87sqsq5aqss43-forc-fmt-0.56.0/bin/forc-fmt) plugin is in a different directory than forc (/nix/store/i0zn8pw77a7zrxm4b7jbz1b1x8cglc0f-forc-0.56.0/bin/forc)

We can either keep it and only show it when --verbose is passed, or remove it entirely.
