Make sorbet and tapioca optional

[JamieMagee]

Sorbet currently doesn't support aarch64-linux. Unfortunately, this means that it doesn't work on Docker on macOS, unless you force --platform=linux/amd64 or DOCKER_DEFAULT_PLATFORM=linux/amd64.

This change makes sorbet and tapioca only install on supported platforms for now. This means that typechecking with srb tc will not work on Docker on macOS. However, while it's an optional, non-enforced, part of the project this is an acceptable trade-off.

Thankfully, it looks like official support for aarch64-linux is extremely close to being completed. So I anticipate this workaround will be shortlived.

• Make build image linux/arm64 compatible sorbet/sorbet-build-image#8

Hmm, that's a bummer, I believe the whole core team is on OSX using Docker :( our codespaces setup is currently not really sufficient, so we might need to invest there a little bit depending on how quickly support for this lands

@jurre do you know how it's split between ARM macs and x86_64 macs? Cause it's only Docker on ARM macOS that would be unable to run srb tc locally.

I verified this builds for me on ARM.

I suspect my editor will still have better completion even though I can't run Sorbet directly but we need a typed file first to test 😄

Somewhere around 50/50 I believe
