Pull request overview

Removes all jQuery integration/support from the OUDS Web JavaScript API and documentation, aligning with upstream Bootstrap’s direction and reducing dependency/bundle surface.

Changes:

• Removed jQuery plugin bridge (defineJQueryPlugin, * .jQueryInterface), jQuery event integration, and jQuery-specific element handling from core JS.
• Deleted/updated unit tests and Karma config that previously validated jQuery behavior.
• Removed jQuery references from docs and dropped jquery from tooling/dependencies (plus updated bundlewatch thresholds).

Absolutely love deleting code 🧹
Just a non blocking question

[MaxLardenois]

Two questions:

• should we remove 'HTML5"? it's quite old now so proabably no need to be specific on the version
• I did not know about this attribute, should we use it more extensively?

[louismaximepiton]

We are never too safe, let people remove it on their side if they want, but I think we can keep it.
The hidden attribute ? I think it's not much used cause there isn't much use cases. But yeah, keep it in mind. We might want to display some new attributes such as inert and others that we don't have ?

On hold until the study about dual mode is done.
