Enable right-side table of contents in MkDocs

[Copilot]

The documentation lacked a right-side table of contents for in-page navigation, similar to BIDS specification and GitHub's markdown viewer.

Changes

• Removed toc.integrate feature from MkDocs Material theme configuration
• This moves the table of contents from the left sidebar to its default right-side position

# mkdocs.yml
theme:
  features: []  # Previously: - toc.integrate

previews

## Result

Before: TOC integrated into left navigation sidebar

After: TOC displayed on right side for in-page navigation

@copilot could you check git history on when we added that toc.integrate here -- may be there is description on why we decided to go that way?

[Copilot]

The toc.integrate feature was added in commit 73ad53b by @yarikoptic on July 27, 2022, and merged via PR #73 on August 30, 2022.

The reasoning from the commit message was:

"Instead of having a separate TOC on the right, it would just expand already present navigation on the left, IMHO making 1. a better use of screen real estate, 2. no longer requiring user to jump with mouse from left to right to navigate"

However, the current issue #216 requests the opposite behavior to match modern documentation sites like BIDS specification and GitHub's markdown viewer, which display the TOC on the right side. The current PR removes toc.integrate to enable that right-side TOC display.

WDYT @kabilar @satra ? boils down to

• consistency with other portals vs more horizontal real estate

[kabilar]

Hi @yarikoptic, I prefer a single, unified navigation which is easier for me to navigate. And provides more space for content.

Is there a dev branch deployment of docs to try out what this feels like?

[yarikoptic]

I don't think we have live preview :-( should be easy to deploy locally though
