You seems to install bash by using official package and use it as
login shell. Right? If so the answer is that official packages for
12.x are built on 12.2-RELEASE. If you build and install bash on
12.3-RELEASE or after 12.2-RELEASE reachs its EoL, the result will
change such as following.

# set | grep -i freebsd
BASH_VERSINFO=([0]="5" [1]="1" [2]="12" [3]="0" [4]="release" [5]="amd64-portbld-freebsd12.3")
MACHTYPE=amd64-portbld-freebsd12.3
OSTYPE=freebsd12.3
