Remove bottles broken by protobuf 27.1

[scpeters]

Part of https://github.com/osrf/homebrew-simulation/issues/2668.

Implemented using:

for m in gz-msgs10 gz-msgs9 gz-msgs8 gz-msgs5
do
    brew bump-revision --remove-bottle-block --message="broken bottle" $m
    for f in $(.github/ci/bottled_dependents.sh $m)
    do
        brew bump-revision --remove-bottle-block --message="broken bottle" $f
    done
done

protobuf 27.1 appears to be ready to merge imminently, so I will preemptively remove these soon-to-be-broken bottles
