Update a URL mentioning dead name

manual backport of #34886

per https://www.w3.org/TR/html-aria/#docconformance

> It is NOT RECOMMENDED to use `aria-disabled="true"` on an `a` element with an `href` attribute.
>
>NOTE
>If a link needs to be "disabled", remove the `href` attribute.

This PR removes the unnecessary `href="#"`, `tabindex="-1"`, and `aria-disabled="true"` from disabled links in both docs pages and examples. `aria-disabled="true"` *is* kept for disabled link-based buttons (that have `role="button"`) as there it's appropriate to use (you *want* to convey to assistive technologies that this thing you're claiming is a button is also disabled at the moment)

Further, the PR extends the "Link functionality caveat" to show the "proper" way (removing `href` and adding `.disabled` class only) to disable a link, but then explains what to do if that's not possible (and then keeps an example with all the traditional `href="#" tabindex="-1" aria-disabled="true"`, but explains clearly that it's not ideal). Same sort of explanation is also added to the pointer event utilities page

Fixes #34353

In case of a modal with fading enabled, a prevented show event can cause show to not showing the modal anymore.

Remove unneeded `.text-white-50` CSS rule

This is already part of Bootstrap 4.6 and 5.0.

Improve and clean up vnu-jar.js

The `thead` rule is safe to remove -- it was a workaround for browsers that didn't conform to this part of the CSS 2.1 spec. (https://www.w3.org/TR/CSS21/tables.html#table-display)
In practice, this meant IE 6 & IE 7.

(thanks to @mattbrundage for this PR upstream for the main.css project (https://github.com/h5bp/main.css/pull/101)

*  Enable `0.x` with negative margins @ v4

I set it as below, but no negative margin was added.
`$spacers: (0\.5: ($spacer * .125));`

After investigating, it seems that `0 \ .5` is also evaluated as 0.
So I changed it to string comparison.

HTML example: `<img class="mt-n0.5">`

*  Clear CI errors
