new 'quick url' for FAIRassist

[allysonlister]

Although we will mostly be directing users to our registry.fairassist.org, it would still make sense to have a quick url going from https://fairsharing.org/fairassist and https://fairsharing.org/FAIRassist to https://fairsharing.org/search?page=1&fairsharingRegistry=fairassist (or whatever the appropriate URL is here)

Thanks!
