Add "Help" page

Added typography_filter.module file with hook_help(). Open MR

Hi

I applied the MR !5 and I confirmed that it implements hook_help and created a help page for the module, I will attach 1 image only for issue's etiquette but rest assured I visited the help page and confirmed that it is accessible.

Merged. Will be released with 8.x-1.1 version
