Update bridge.version to latest released bridge when 0.32.0 is out

[ppatierno]

This PR #11032 changed the way the HTTP bridge configuration is set up by the operatorot, not using env vars anymore but a ConfigMap.
Those changes needed corresponding changes in the bridge with this PR strimzi/strimzi-kafka-bridge#963 but, of course, the new version (0.32.0) of the bridge is not released yet.
For this reason and for running the STs successfully in the operator repo, I had to change the bridge.version file to "latest" and run the make bridge_version command in order to push the packaging files being used by STs in order to run the latest, not released yet, bridge version.
When the bridge 0.32.0 is out, we'll need to update the bridge.version file properly with the released version. It has to be done, of course, before the new operator release 0.46.0.
