Replace bundle_type_id with Label for Page Title / Routing

Currently, when using a Form Mode to Create a new Bundle able Entity , the displayed Title is:

"Create" %bundle_id "as" %form_mode_label

This is confusing for non coders (Content Managers) because it does not match the Human readable Label (good) shown on the Title when editing and existing Entity.

I have a patch, that injects the 'entity_type.bundle.info' container into `\Drupal\form_mode_manager\Controller\FormModeManagerEntityController`and then creates all Route Controllers (factories) passing that into their constructors and then alters \Drupal\form_mode_manager\AbstractEntityFormModesFactory::pageTitle

Note: The way the Abstract Class is defined requires me to pass the same container, even for controllers that are not bundle aware. But it seems to be an overkill to have two different Abstract Classes, or override the Constructor for those who don't match. Also injecting a dependency does not seem to affect performance.
