Remove the `show` property from the modal plugin (#32279)

Drop the support of show property from the modal plugin.
When creating the new modal instance in v5, the `show` property does not work anymore, so instead of fixing the behavior just removing it permanently to keep the consistency between all the plugins. (All other plugins require the `show()` method to be called on the instances to be shown)

tooltip.js: reuse existent variable

Add tests

Extra check for existence of any `aria-label`

before overwriting it...

Accessibility update for tooltip.js

Update to the tooltip.js to add an aria-label attribute that contains the original title of the element, but only if the element doesn't have an existing aria-label attribute.

This is to address cases where screen readers are not capturing the aria-describedby attribute that is added when the tooltip is triggered.  This should also avoid a race condition between the screen reader and the appearance of the tooltip.

Keep rounded corners for the first .btn in vertical button group (#31303)

Remove default linear gradient (#32277)

Remove the default invisible gradient causing the performance issue in #32266. By removing the custom property, the linear gradient will become invalid, thus not appear by default.

There can still be a performance issue with striped tables though.

Improve build/generate-sri.js regex (#29753)

When using single-quotes in config.yml, the previous
regular expression in build/generate-cli.js wasn't working correctly,
it was replacing ALL string values with hashes.
Now both double- and single-quotes can be used in config.yml,
and the RegExp will work as expected.

Also, allow trailing whitespaces and empty ("") values to be matched.

Docs: fix homepage npm install version (#32194)

Docs: change sidebar collapse controls to actual button elements (#31098)

apart from the visual styling, there's probably no good reason why these shouldn't be `<button>` elements, semantically

the buttons still look a shade too button-like, despite using `.btn-light`. the last remnant of button styling can probably be suppressed further, *or* this makes the case for expanding the core button styles to have one that looks completely non-button and non-link like (for cases where an additional style/hint was given already, or it's clear from context that something's an actionable button or link)
