Bug#1109655: Must use Breaks/Replaces instead of Conflicts to allow smooth transition

Also, the `Conflicts: protoc-gen-go` will be an issue, for the same reason.

Bug#1109655: Must use Breaks/Replaces instead of Conflicts to allow smooth transition

Severity: serious

As can be seen below, the use of "Conflicts" does not allow for a smooth 
transition.

This is policy 7.6.1 - Breaks/Replaces is the normal mecanism for packages 
overwriting files of other packages.

Hi all,

  I mentioned this on the IRC channel, but am also bringing it up here.
A couple of days ago a handful of bookworm -> trixie upgrade bugs were
reported, all relating to packages that depend on protobuf: #1109513,
#1109514, #1109515, #1109516, #1109517.

  The root cause in each bug seems to be the golang-github-golang-
protobuf 1-3 -> 1-5 transition. Here's what apt reports:
