Patternlab and PHP 8.1?

[lquessenberry]

i am trying to upgrade PHP version of pattern lab to work with PHP 8.1. So far this is what I am getting.

Problem 1
- doctrine/collections is locked to version v1.4.0 and an update of this package was not requested.
- doctrine/collections v1.4.0 requires php ^5.6 || ^7.0 -> your php version (8.1.13) does not satisfy that requirement.
Problem 2
- doctrine/collections v1.4.0 requires php ^5.6 || ^7.0 -> your php version (8.1.13) does not satisfy that requirement.
- pattern-lab/core v2.9.0 requires doctrine/collections 1.4.0 -> satisfiable by doctrine/collections[v1.4.0].
- pattern-lab/core is locked to version v2.9.0 and an update of this package was not requested.

Seems like this is a known issue.
