BUG: Beta11 not installable: neos/contentrepositoryregistry-storageclient 9.0.0-beta11 -> could not be found in any version

[mhsdesign]

When tagging the beta we found a regression too late.

💡 Composer conflicts after updatating / for new installations

Setting up a new project via composer create-project neos/neos-base-distribution:9.0.0-beta11 or updating your project will still reference the package neos/contentrepositoryregistry-doctrinedbalclient.
It was dropped and neos/contentgraph-doctrinedbaladapter needs to be referenced instead! Composer create will be fixed with beta12

see https://discuss.neos.io/t/neos-9-beta-11-release/6618

We have to adjust https://github.com/neos/neos-base-distribution/blob/6ba2395a44446060f62cc2ee08ac89052bac9bc5/composer.json#L30 (and neos/diff etc should also be dropped btw)
