Fix #573 by updating spatie/laravel-ignition

[rmartinoscar]

• [x] Update spatie/laravel-ignition to ^2.8 instead of ^2.7 so its based on spatie/ignition ^1.15 instead of ^1.14

• [x] Edit the clean script in package.json#L134 to remove cd, set --no-interaction and add manifest.json

• [x] Change getDocumentationLinks cause the link given was dead

• [ ] The composer.lock & yarn.lock havn't been updated in ages maybe it's time, same goes for the mysql schema

This can't be merged without updating composer.lock
