Rename Paragraphs Bundle Permissions to Paragraphs Type Permissions

[laryn]

We've changed the public-facing language from "bundle" to "type" but the submodule is still currently named Paragraphs Bundle Permissions.

I'm changing the front-facing language in this sub-module to match the main module, and in some of the comments a blended approach (type/bundle) until I get a chance to do a more thorough combing-through of the entire module, adding deprecations for function names, updating permission names, etc. in #23
