Install scripts should support non-interactive mode

[jdetter]

I didn't know you can do this, but if you're doing a curl script.sh | sh -s type invocation you can actually pass params to that via:

curl https://sh.rustup.rs -sSf | sh -s -- -y

We should do this!

We think this is a P1 related to something about the root directory in the new directory structure... but we can't currently pinpoint why.

okay no it's actually about being able to install inside a docker image

we think there's some reason that we can't just pipe a custom stdin to the script

if you go to our website and download the docker container, it's spacetimedb-standalone, not e.g. the CLI.

We want to host this script on the website
