chore: Release stackable-operator 0.77.0

[sbernauer]

Description

One could argue this is a bugfix release, but let's play it safe

Fixed

• Fix the logback configuration for logback versions from 1.3.6/1.4.6 to 1.3.11/1.4.11 (#874).
• BREAKING: Avoid colliding volumes and mounts by only adding volumes or mounts if they do not already exist. This makes functions such as PodBuilder::add_volume or ContainerBuilder::add_volume_mount as well as related ones fallible (#871).

Changed

• BREAKING: Remove the unique_identifier argument from ResolvedS3Connection::add_volumes_and_mounts, ResolvedS3Connection::volumes_and_mounts and ResolvedS3Connection::credentials_mount_paths as it is not needed anymore (#871).
