Add sentence about searching on ct log monitors (#1451)

We frequently see users on the Community just copy/pasting the expiry
email. Usually I redirect them to this documentation page. It's almost
always necessary to explain what happens using crt.sh. I believe it
would be a good thing if the documentation page I link to, also includes
the part about ct log monitors as explained on the Community threads.
That way one could not say the documentation is incomplete with regard
to what happens in the Community threads.

This relatively simple addition refers to the use of ct log monitors to
see a history of your certificates. This complements the part above it
about adding/removing hostnames. Users might not remember doing that, so
seeing the history on crt.sh is quite helpful I think and thus helpful
to include it here.
