(www) Split up docs and blog page creation

[tesseralis]

Description

Split up the logic for creating pages for docs and blogs.

Motivation

Both docs and blog posts are MDX files with the same source, but they usually have different logic associated with them, leading to a lot of branched paths and queries based on path.

Relying on allMdx for all these queries makes it hard to reason about and prone to error, since other sources may also have MDX (for example, we're potentially creating duplicate package READMEs here.

Steps

Once #21217 is merged, split utils/node/docs.js into two files: docs.js and blog.js.

In docs.js:

• onCreateNode should find MDX or markdown files that have a absoluteFilePath of docs (or the translation sources gatsby-{lang} and create a new child node DocPage.
• all places that query MDX looking for docs, such as createPage and the docs template, should query allDocPage or docPage instead of allMdx.

In blog.js:

• onCreateNode should find MDX or markdown files that are have an absoluteFilePath of blog and create a new child node BlogPage.
• All places that query MDX looking for blog posts, such as createPage and the blog templates/pages, should query allBlogPost or blogPost instead of allMdx/mdx.
