Added documentation for using checkboxes to toggle collapse

[TommasoAllegretti]

Description

The Collapse documentation only talks about buttons and elements as toggles. However, using checkboxes also works fine. Therefore, it should be pointed out in the docs that you can also use checkboxes as collapse toggles.

I'd say that we shouldn't mention checkboxes specifically but rather make it understandable that collapse can be used with basically everything. For example, you can also use it with basic HTML elements such as <code>, <div>, etc.

<code data-bs-toggle="collapse" data-bs-target="#collapseExample">Test from code</code>
<div data-bs-toggle="collapse" data-bs-target="#collapseExample" class="w-100 h-100 bg-warning">Test from div</div>
<div class="collapse" id="collapseExample" style="">
  <div class="card card-body">
    Some placeholder content for the collapse component. This panel is hidden by default but revealed when the user activates the relevant trigger.
  </div>
</div>

Maybe we can make it clearer in "How it works" that it works with everything and that buttons and links are used on this page because they would be the most common elements as triggers 🤷

Agreed, we are better off documenting the above. Let alone that the checkbox in this PR is hard to notice next to the buttons.

Sorry for the delayed response, I followed your feedback and changed the documentation accordingly.
Please let me know if the documentation is now clear enough in explaining the possibility of using various different elements to toggle a collapse.
