Jan Drewniak 7e81c26712 [TOC] Remove pointer-events:none on .sidebar-toc-link
Previously, we relied on setting pointer-events:none on all child
elements of ToC links.

This propagated the click event up to the link itself in Javascript
and allowed us check if an element with the class `.sidebar-toc-link`
was clicked.

Unfortunately as of Chromium 101 this approach causes the entire link
in the sidebar to be unclickable.

Instead, this patch checks if the ToC link or any of it's children
have been clicked (using the less efficient `Element.closest()` ).

Nicholas Ray 29e40714bc Offset the TableOfContents top property only when the sticky header is shown
This uses the sticky header's `.mw-sticky-header-element` utility class
to conditionally offset the table of contents to the height of the
sticky header only when the sticky header is enabled.

Jan Drewniak 7d32ec80d3 Collapse ToC by default & expand sections when clicking section headings
Collapses sub-sections in the new table of contents by default
(except for non-js and reduced-motion users) and expands the
sections when the top-level section link has been clicked.

Refactors the `activateSection` TableOfContents methods into separate
`activateSection` and `deactivateSection` functions.
Adds `expandSection` and `collapseSection` methods.

Adds triangle icon as a visual expand/collapsed indicator
next to all ToC section headings and are hidden via CSS based on
whether or not the section contains subsections.

Adds test for tableOfContents.

Nicholas Ray 3c433a5315 Add sectionObserver and tableOfContents component JS to respond to intersection changes
This commits sets up the Table of Contents to bold the active section
when the section is scrolled.

Unfortunately, because our content does not have actual sections but
instead has a flat list of headings and paragraphs, we can't use
IntersectionObserver in the conventional way as it is optimized to find
intersections of elements that are *within* the viewport and the
callback will not reliably fire during certain scenarios (e.g. with fast
scrolling or when the headings are not currently within the viewport).
Furthermore, iterating through a list of elements and calling
`getBoundingClientRect()` can be expensive and can also cause
significant forced synchronous layouts that block the main thread.

The best compromise in terms of performance and function that I've found
is to use a combination of a throttled scroll event listener and
IntersectionObserver's ability to asyncronously find the
boundingClientRect of all elements off the main thread when `.observe`
is called which is the approach this patch takes. Although this is an
unorthodox way to use IntersectionObserver, performance profiles
recorded while holding the "down" arrow and scrolling for 10 seconds
with a 6x CPU throttle are comparable between master and this patch:
