[BUGFIX] Raise minimum version for typo3/cms-composer-installers

typo3/cms-composer-installers conflicts with specific
composer/installers versions, but this conflict was unfortunately wrongly 
specified. This is now fixed upstream, but we need to update
the TYPO3 core dependencies as well to require the fixed version.

Resolves: #76617
Releases: master, 7.6, 6.2
