Update Laravel docs

[stayallive]

This updates a few things in the Laravel documentation:

• Mentions Laravel/Lumen 5 & 6 (instructions are the same)
• Group installation instruction under "Installation" menu
• Update laravel specific config to use the correct syntax (old one will work but new one is preffered)
• Mention all PHP SDK options are supported
• Group configuration under "Configuration" menu
• Document decorating the client builder: Allow for decorating the client builder sentry-laravel#290
• Add queue section: Docs could have a "queue" section sentry-laravel#298
• Fix/update user feedback snippet (ref)

/cc @HazAT (& @Jean85 & @ste93cry for textual / PHP SDK bits)

For what I can understand of Laravel, this LGTM 👍

@HazAT yeah it was! Also I needed to restart bin/server each time for changes to show 😄

If you could take a pass to see if there aren't any weird sentences in it that would be appreciated. But I think this is ready to 🚢 now.
