[PATCH] Documentation/rv: Replace stale website link

[Gabriele Monaco]

The sched monitor page was linking to Daniel's website which is now
down. The main purpose of the link was to point to a source for the
models from the original author and that can be found also in his
published paper.

Replace the link with a reference to Daniel's "A thread synchronization
model for the PREEMPT_RT Linux kernel" which can be found online and
includes the models definitions as well as the work behind them (not the
original patches but since they're based on a 5.0 kernel and are mostly
included upstream, there's little value in keeping them in the docs).
