build: temporarily increase the commit msg limit to 120

Right now HEAD and 5.0.x have a branch deviation and therefore
all the commits between both branches are being compared. There
exists a problematic commit which has a commit message that is
longer than 100 commits. This patch will temporarily increase
the limit to 120 so that CI passes. Once master is resumed to
being the primary development branch (once 5.0.0 is out) then
the the msg limit will be set back to 100.
