Composer conflict because phpstan/phpdoc-parser is locked to ~1.5.0

[gndk]

When trying to update to 2.4.0, composer install fails because of a conflict. In my case its doctrine/coding-standard, but there could probably also be conflicts with other packages.

The reason is that phpstan/phpdoc-parser was locked to ~1.5.0 (which is a relatively old version, current is 1.9.0) in this commit: 16e8192

The commit message is not related to adding this requirement, so I'm not sure if this was added by accident.

Is locking the phpstan/phpdoc-parser version really necessary or can this tight version constraint be removed again?

Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Root composer.json requires doctrine/coding-standard 10.0.0 -> satisfiable by doctrine/coding-standard[10.0.0].
    - doctrine/coding-standard 10.0.0 requires slevomat/coding-standard ^8.2 -> satisfiable by slevomat/coding-standard[8.2.0, ..., 8.5.2].
    - slevomat/coding-standard[8.2.0, ..., 8.3.0] require phpstan/phpdoc-parser ^1.6.2 -> satisfiable by phpstan/phpdoc-parser[1.6.2, ..., 1.9.0].
    - slevomat/coding-standard[8.5.0, ..., 8.5.2] require phpstan/phpdoc-parser >=1.7.0 <1.9.0 -> satisfiable by phpstan/phpdoc-parser[1.7.0, 1.8.0].
    - slevomat/coding-standard 8.4.0 requires phpstan/phpdoc-parser >=1.7.0 <1.8.0 -> satisfiable by phpstan/phpdoc-parser[1.7.0].
    - You can only install one version of a package, so only one of these can be installed: phpstan/phpdoc-parser[1.5.0, ..., 1.9.0].
    - weirdan/doctrine-psalm-plugin v2.4.0 requires phpstan/phpdoc-parser ~1.5.0 -> satisfiable by phpstan/phpdoc-parser[1.5.0, 1.5.1].
    - Root composer.json requires weirdan/doctrine-psalm-plugin 2.4.0 -> satisfiable by weirdan/doctrine-psalm-plugin[v2.4.0].

I just saw #120

@AndrolGenhald mentioned that the constraint should be removed again after doctrine/coding-standard has a 9.x release, so it seems like this is a leftover.
