docs: Proposal: list playbook keywords with "Applies to" flags

[moreati]

SUMMARY

The playbook keywords reference is currently organised by category, then applicable keywords.

I propose reorganising this, to list all keywords at the top level, each with an "Applies to" block. The PR shows a demonstrator. It isn't intended to as a polished, styled final design.

ISSUE TYPE

• Docs Pull Request

COMPONENT NAME

ADDITIONAL INFORMATION

The motivations for this proposed reorganisation are

• Make it easy to link to one canonical reference for a given keyword
• Make it easier to see what categories/levels a given keyword applies to
• Reduce repetition of keyword descriptions on the page

I hope the following table and screenshot illustrate the concept

Current organisation	Proposed organisation
Play any_errors_fatal    [description] become    [description] ... Role any_errors_fatal    [description] become    [description] ...	action Applies to: ✗ Play ✗ Role ✗ Block ✓ Task [description] always Applies to: ✗ Play ✗ Role ✓ Block ✗ Task [description] ...

This is an interesting enhancement, thanks @moreati. We are in the midst of changing our docs pipeline to work with collections, so it may take us some time to get to this.

some people prefer to look at it by the object, I would prefer to not replace the existing page but compliment it and have each link to each other.

compliment it and have each link to each other

I'll iterate the prototype on that basis
