Adding configurable team resolver for permission team id

[adrenallen]

This adds a configurable team resolver to the permission registrar class.

This allows users to implement their own storage for the team id. This is useful if you are setting a current_team_id on the user table similar to how jetstream works..

By implementing a resolver in this way, the middleware approach is optional as the resolver will always go through your logic via CLI, HTTP, or otherwise. Which means less explicit calls to setPermissionsTeamId.

We are defaulting to the DefaultTeamResolver so that we are backwards compatible with anyone that already has the config published.

Let me know if more tests are desired, I felt that the current tests did a good job covering the setting and getting of team permission id.

Example of a custom resolver:

App\Permissions\CustomerTeamResolver.php

class CustomTeamResolver implements PermissionsTeamResolver
{
    public function setPermissionsTeamId($id): void
    {
        if ($id instanceof \Illuminate\Database\Eloquent\Model) {
            $id = $id->getKey();
        }

        if (auth()->user()) {
            auth()->user()->current_team_id= $id;
            auth()->user()->save();
        }
        
    }

    public function getPermissionsTeamId() : int|string|null
    {
        return auth()->user()?->current_team_id;
    }
}

config/permission.php

...
'team_resolver' => \App\Permissions\CustomTeamResolver::class,
...

For context, this is how I accomplished this same functionality prior to this PR:

AppServiceProvider.php

class AppServiceProvider extends ServiceProvider
{
    /**
     * Register any application services.
     */
    public function register(): void
    {
        $this->app->beforeResolving(\Spatie\Permission\PermissionRegistrar::class, function () {
            $this->app->singleton(\Spatie\Permission\PermissionRegistrar::class, PermissionRegistrar::class);
        });
    }

PermissionRegistrar.php

<?php

namespace App\Providers;

class PermissionRegistrar extends \Spatie\Permission\PermissionRegistrar
{
    /**
     * Set the team id for teams/groups support, this id is used when querying permissions/roles
     *
     * @param  int|string|\Illuminate\Database\Eloquent\Model|null  $id
     */
    public function setPermissionsTeamId($id): void
    {
        auth()->user()->current_organization_id = $id;
        auth()->user()->save();
    }

    /**
     * @return int|string|null
     */
    public function getPermissionsTeamId()
    {
        return current_organization_id();
    }
}
