Support new error solutions package

[freekmurze]

This PR adds support for the new error solutions package.

This solutions package is extracted out of the old Ignition error package so we can use it in both the new Flare client package and new package to display solutions on the default Laravel error page.

We're seeing errors in our projects without this fix. Any change to get this merged & released?

i.e.

PHP Fatal error:  Uncaught TypeError: NunoMaduro\Collision\Adapters\Laravel\IgnitionSolutionsRepository::__construct(): Argument #1 ($solutionProviderRepository) must be of type Spatie\Ignition\Contracts\SolutionProviderRepository, Spatie\ErrorSolutions\SolutionProviderRepository given, called in /home/michel/code/enflow/clients/xxx/vendor/nunomaduro/collision/src/Adapters/Laravel/CollisionServiceProvider.php on line 49 and defined in /home/michel/code/enflow/clients/xxx/vendor/nunomaduro/collision/src/Adapters/Laravel/IgnitionSolutionsRepository.php:26
