runtime: clarify GOROOT return value in documentation
The current GOROOT documentation could indicate that changing the
environment variable at runtime would affect the return value of
GOROOT. This is false as the returned value is the one used for the
build. This CL aims to clarify the confusion.
Fixes #22302
