(#3228) Throw earlier if .Net 4.8 is not present

There are instances where .Net is not installed in a way that allows
Chocolatey CLI to function. In these scenarios, the version in the
registry seems to be very old. This commit moves the test for .Net 4.8
earlier in program execution in order to provide a more user friendly
error message.

Additionally, this changes the check to use Registry64 instead of
Registry32, as on 64 bit systems the 64 bit registry is the one that
determines the .Net version. And the lookup on 32 bit systems gracefully
falls back to the 32 bit registry.
