feat(autojump): add new Homebrew default path on M1 Macs (#9637)

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.
