[TASK] Avoid typo3/cms-install

TYPO3 v13 no longer hard requires EXT:install. In the
spirit of a "minimal" meta package, it should no
longer be part of composer.json.

Deploying production systems without the install tool
raises security, since not existing code can not have
security issues.

Instances that manage good deployment chains and can
deal with a missing EXT:install during upgrades
(or have it loaded temporarily, or only on some of
multiple production servers), should have the
opportunity to do so.
