Changes in php-opencloud/openstack are unrelated

That happened because most numbers are "fixed" with ^X.Y instead of ^X.Y.Z which means it also installs any X.(Y+1) so it updated 3.1.z to 3.2.a because that now works as 8.0 is the minimum....

if you change composer.json and run composer update php no other deps should be touched

Actually I remembered wrong, I did what you said and had:

> composer update php --no-dev
Gathering patches from patch file.
No patches supplied.
Loading composer repositories with package information
Updating dependencies
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - php-opencloud/openstack is locked to version v3.1.0 and an update of this package was not requested.
    - php-opencloud/openstack v3.1.0 requires php ^7.2.5 -> your php version (8.0; overridden via config.platform, actual: 8.1.2) does not satisfy that requirement.

Which is why I also updated this lib.
