Auto merge of #2224 - Turbo87:jquery, r=locks

Remove jQuery

Following #2209 there does not seem to be any code left that relies on jQuery being available. This PR removes jQuery from the build which leads to 30kB (~10%; after gzip) less JS code shipped to the clients.

@jtgeibel @carols10cents we might want to do a round of QA on the staging server for this to ensure that I haven't missed anything 🙏
