[IA Research] Identify a solution for categories

[caylahamann]

Summary

Currently there is a three category (layer) structure reflected in the doc URL, we want to recreate this for the current docs site but we want the flexibility to not be locked into this structure.

Procedure

Open up a PR merging into research. If there is no changes in the code (and only research details), you can just make an edit in a text file, since there is no plan to merge this into main. Use the PR template research_PR_template.md either by coping the markdown into the PR or by appending the query string ?template=research_PR_template.md to the URL. Fill out the template by answering the research questions listed below.

Research Goals

• Investigate solutions for the taxonomy (categories) that can be reflected in the URL
• Discuss solutions with engineers, content creators and PMs to determine best path forward
