On some Macs (e.g. M1, 2020), `uname` returns 'Darwin' and `uname -m`
retuns 'arm64', this case is not handled in shell-integration. As a
result, ssh kitten transfer fails with:
>> Unknown CPU architecture arm64
Fix this by adding the case for arch=arm64 in kitten and kitty
shell-integration scripts.
Tested this on Mac Pro (M1, 2020).
It's easier to type, and cuter.
Also, most, if not all of the TUI parts of
kitty's kittens will eventually be re-written into kitten.
The only downside I can see is that we cant tab complete kitty
anymore, but hopefully there will be less reason to run kitty
from the shell as command line tools migrate to kitten.
Meowrrrr!!!
