Refactor branch/tag selector dropdown (first step) (#23394)
Follow: * #23345 The branch/tag selector dropdown mixes jQuery/Fomantic UI/Vue together, it's very diffcult to maintain and causes unfixable a11y problems. It also causes problems like #19851 #21314 #21952 This PR is the first step for the refactoring, move `data-` attributes to JS object and use Vue data as much as possible. The old selector `'.choose.reference .dropdown'` was also wrong, it hits `<div class="choose reference"><svg class="dropdown icon">` and would cause undefined behaviors. I have done some quick tests and it works. After this PR gets merged, I will move the code into a Vue SFC in next PR.   --------- Co-authored-by: techknowlogick <techknowlogick@gitea.io>
