Composer: support non-semver versions

[rarkins]

Describe the proposed change(s).

Apparently composer/packagist packages are not limited to semver for example: https://semver.madewithlove.com/?package=shopware%2Fadministration

#28297 has been created to support such versions properly in composer versioning.

For this issue, we should check the existing version if it is semver-compatible and if not then switch to loose versioning. In cases where a non-semver locked version exists but composer.json uses a range syntax then we will need to skip it.

i.e.

• If currentValue and lockedVersion are the same, non-semver version - valid loose versions - then switch to loose
• If lockedVersion is non-semver and currentValue is a constraint, add a skipReason
