Check if you are running arm64 or amd64 brew

With the switch to m1. Most people will still be running the amd64 version of brew, which will be going through a translation layer all the time.

Run 
```shell
which brew
```
If you get ```/opt/homebrew/bin/brew```

Then you are using the correct arm version.

If you get ```/usr/local/bin/brew```

You are still using the amd64 version.

You can follow the following if you want to switch.
