Let toc is visable through Page & Section variables in templates

Sanity check:

• Have you checked to ensure there aren't other open Pull Requests for the same update/change?

Yes

Code changes

• Are you doing the PR on the next branch?

Yes

If the change is a new feature or adding to/changing an existing one:

• Have you created/updated the relevant documentation page(s)?

Yes

Is that specifically for #694 or did you need that yourself?

The PR itself looks good, although it might be worth it removing the current toc variable from page/section to avoid serializing it twice.

Yes, kind of some case like #694 .

It is better that the toc could be removed from page & section, but there would be a break change.

That's fine, next version is planned to have breaking changes.
