Update the layout of the JSON RPC page

[eshaben]

This PR reformats the JSON RPC page as follows:

• Removes the section categorization because I feel like people are going to use this page as a quick reference so it should just be alphabetized so users can more easily find what they're looking for
• Sets the section headers to be the rpc method name for the same reason as above
• Defines parameters even when there are none and sets the parameter types along with links back to the Ethereum docs for more info on data, quantities, and default block parameters
• Moves the examples out of admonitions, as they shouldn't be hidden or be highlighted. Especially since the main purpose of this page is to showcase what's available along with quick copy/paste examples

Looks like people have been skipping the formatter cause a bunch of pages were committed too 👀 🙅🏻‍♀️
