feat: upgrade default app version to v2.55.0

[eliobischof]

⚠️ BREAKING CHANGE

The default ZITADEL version is now v2.55.0.
This requires Cockroach DB to be at >= v23.2
If you are using an older version of Cockroach DB, please upgrade it before upgrading ZITADEL.

Note that in order to upgrade cockroach, you should not jump minor versions.
For example:

# install Cockroach DB v23.1.14
helm upgrade db cockroachdb/cockroachdb --version 11.2.4 --reuse-values
# install Cockroach DB v23.2.5
helm upgrade db cockroachdb/cockroachdb --version 12.0.5 --reuse-values
# install Cockroach DB v24.1.1
helm upgrade db cockroachdb/cockroachdb --version 13.0.1 --reuse-values
# install ZITADEL v2.55.0
helm upgrade my-zitadel zitadel/zitadel --version 8.0.0 --reuse-values

Please refer to the docs by Cockroach Labs. The ZITADEL tests run against the official CockroachDB chart.
