BREAKING CHANGE: the `gmt` alias conflicts with the Generic Mapping Tools command.

`gmtlvim` for consistency.

Fixes #9154

On M1-Macs homebrew uses /opt/homebrew as default location for ARM
packages. This results in the autojump plugin not being able to find
autojump after a clean default installation.
This commit adds the new default location to the autojump plugin.

Homebrew on Mac M1 is moved to the /opt/Homebrew location. This change updates the search
locations with this path.
