Bump Citus version into 13.0.0 (#7792)

We are using `release-13.0` branch for both development and release, to
deliver PG17 support in Citus.

Afterwards, we will (probably) merge this branch into main.

Some potential changes for main branch, after we are done working on
release-13.0:
- Merge changes from `release-13.0` to `main`
- Figure out what changes were there on 12.2, move them to 13.1 version.
In a nutshell: rename `12.1--12.2` to `13.0--13.1` and fix issues.
- Set version to 13.1devel
