Refactor Schema and Schema Data Related Documentation

[bflad]

Module version

v0.10.0

Use-cases

The website documentation is less than ideal as it has quite a few schema-related pages as top-level in the lengthy side navigation. In particular:

• https://terraform.io/plugin/framework/accessing-values
• https://terraform.io/plugin/framework/paths
• https://terraform.io/plugin/framework/path-expressions
• https://terraform.io/plugin/framework/schemas
• https://terraform.io/plugin/framework/writing-state

It would be clearer if these were bundled together as they are conceptually related.

Proposal

Create a new top-level section named "Schemas and Schema Data" or "Schemas and Config/Plan/State" with the following:

• Overview page, brief introduction to the concepts and linking to others
• Redirected accessing values page
• Redirected paths page
• Redirected path expressions page
• Redirected schemas page (maybe "Schema Definitions"?)
• Redirected writing state page (probably should not say state as it also related to setting the plan in plan modifiers)

Doing this will likely warrant fixing wording/flow for all the concepts/pages to ensure they seem cohesive together.

This updated documentation should also contain a reference page for schema block support.

The updated documentation should also contain complex data modeling and provider logic (e.g. nested lists, nested attributes)
