`-y` to accept prompts in non interactive sessions

[Hypnotist1148]

At the moment I do it like this

rtx install myplugin@latest
rtx global myplugin@latest

But it would be nice to base able to this

rtx global myplugin@latest -y

just set RTX_MISSING_RUNTIME_BEHAVIOR=autoinstall

I'd be open to making this a global flag. I don't like -y though. It's not clear what you're saying yes to, right now we only prompt for this one thing but we may add other things later. I think granular prompts would be better.

--missing-runtime-behavior=autoinstall is certainly a mouthful, but that might be the best option unless we want to consider changing this to something more concise. Another advantage of this is that it matches the setting and env var.

True, something like --install-missing

it's actually an accident you were even able to pipe in "y". That was happening because I check if stderr is a tty, but not stdin. Note this prompt has also changed to multiselect so you should still be able to do that but you wouldn't need to pass "y" since everything defaults to enabled.
