Minor doc updates

Addresses the following issues:
- Remove Mojaloop mention on payment method page
- Spell out all instances of OP and WM as Open Payments and Web Monetization, respectively
- Minor additions and tweaks to Overview and Open Payments Concepts pages with input from Sarah's blog post

#490

Also took care of updating reference from Open Payments API to Open Payments APIs (plural, no apostrophe)

#456

 In Open Payments, a grant indicates a transfer, or delegation, of authorization from a resource owner (RO) to a piece of software. An RO can be a physical person, such as the software’s end user, or a process, such as predefined organizational rules. By delegating authorization, the RO allows the software to access and perform operations on protected resources on the RO’s behalf.

 ## Grant requests
 
-Before a client can access the Open Payments API, it must send a grant request to the AS. The request must contain the type of resource it wants to work with and the action(s) it wants to take on the resource. Resource types include `incoming-payment`, `quote`, and `outgoing-payment`. The available actions depend on type, but examples include `create` and `read`. A successful grant request results in the AS returning one or more access tokens.
