don't register the runner if the version is not allowed

[colemickens]

Describe the bug
It seems that an outdated runner is very able to register. Which it can do in a loop. And then exhaust every available runner registration.

It seems to me that GHA infrastructure should just... not register the invalid runner at all, but I suspect it will be easier to effect change here.

Could the runner find out if it's a supported version and bail before even trying to register if it's too old?

To Reproduce
Steps to reproduce the behavior:

1. Run a runner, set it to auto-restart on any failure
2. Let it go a bit stale

Expected behavior
GHA to... reject invalid runners rather than register a runner that is, de facto, useless.
