Documentation tasks

Rewritten docs. Some things to document:
- formrequests: supported rules
- hideFromAPIDocumentation
- overwriting with --force
- binary responses
- troubleshooting: --verbose
- plugin api: responses - description, $stage property
- --env
- Use database transactions and create() when instantiating factory models

Release blocker

Port recent changes from old repo

Features

File upload input: see https://github.com/mpociot/laravel-apidoc-generator/issues/735 . The primitive type file has already been added to FormRequest support, but with no example value
Command scribe:strategy: It would be nice if we had a make strategy command that can help people generate custom strategies
Possible feature: https://github.com/mpociot/laravel-apidoc-generator/issues/731

Improvements

Improve error messaging: there's lots of places where it can crash because of wrong user input. We can try to have more descriptive error messages.

Tests

Add tests that verify the overwriting behaviour of the command when --force is used
