restrict composer in php 7.4 to 2.2

[jheimbach]

With the release of composer 2.3, the pimcore post scripts in pimcore 6 are broken:

In Process.php line 143:

  [TypeError]

I propose to restrict composer to version 2.2 in the php 7.4 container

All committers have signed the CLA.

[jdreesen]

Sounds reasonable, as Composer v2.2 is an LTS version.

[dpfaffenbauer]

had the same issue already too

[dpfaffenbauer]
