Problem 1
- This package requires php ^8.0.6 but your PHP version (8.0.5) does not satisfy that requirement.
The earlier suggestion was to use the config key in the composer.json to fake a PHP version. I would not be liberal with its use; only in the circumstances such as yours, for a patch release. The point is some dependency has specified a minimum 8.0.6 version, so you need to find a way to either support or fake that requirement. This should be a temporary measure until Forge supports the minimum requirement of that particular package.
