Formulas' Docker Runner images need to be made available for arm64/v8 to support Apple Silicon

What version of Rit are you using (rit --version)

2.11.3

Does this issue reproduce with the latest release

Yes

What operating system are you using

MacOS 11.4

What did you do

Tried running the Powershell Formula template with the Docker runner

What did you expect to see

The Formula's output in STDOUT. It's possible we might need changes to Ritchie itself to support multiple CPU architectures and dynamically detect/use them, but I think that providing the arm64 Docker images will be enough.

What did you see instead

WARNING: The requested image's platform (linux/amd64) does not match the detected host platform (linux/arm64/v8) and no specific platform was requested
Failed to resolve full path of the current executable [/proc/self/exe]
Error: exit status 133
