HEADS UP: hashes changing for the freebsd-ports repo on Sunday

[Ulrich Spörlein]

Hi folks,

It's another one of those instances where the hashes will change 
(starting with all commits from Jan 5th 2021 forward).

Our latest ports committers were not added to the authormap file in time 
_and_ this stopped being a fatal issue in the converter a while ago :/

Please bear with us a while longer.
Thanks
Uli

PS: This also affects the src and doc repos, but they will obviuously 
not be changed again, see the errata notes at
