Fix empty dropdown

Deselecting the current selected option on a dropdown they were removing the input related to them.
This led to a unexpected cases. The forms were submitted without all required inputs and the label was still indicating an option was selected. This MR fixes that.

See merge request !5927

17465 Fixed dropdown cursor key navigation

## What does this MR do?
This MR fixes the use of cursor/arrow/enter key events with search dropdowns, allowing a user to navigate up and down the list with the arrow keys and then select their item with the enter key.
It also applies some *minor* scroll user experience fixes, such as resetting the selected dropdown item every time it opens/closes (also stops multiple dropdowns conflicting) and forcing the dropdown scroll to scroll right to the top or bottom depending on whether they have selected the first or last item, respectively.

## Are there points in the code the reviewer needs to double check?
I would like someone with GitLab experience to check over whether this would harm any unique implementations of the GitLabDropdown or SearchAutocomplete.

## Why was this MR needed?
The current version has incorrectly behaving search dropdowns in the navbar, they either do not navigate using the keyboard or do not use the enter keystroke to select a highlighted item.

## What are the relevant issue numbers?
Fixes #17465.
Closes #20752.
Closes #21014.
**Contributes** to #20754.

Ace ventura

## What does this MR do?

Makes Ace only load when it's actually necessary. The only two places it seems to be used is for Snippets and the File (Blob) Editor.

Before minification or compression, this takes the application.js down from 2.2MB to 1.6MB, and also removes two inline scripts :D

Compressed/Minified: master: 317KB/1.1MB, ace-ventura: 220KB/771KB

## Are there points in the code the reviewer needs to double check?

That this doesn't just completely break anything.

## Why was this MR needed?

Ace is a big library, this allows us to only load it when necessary.

## What are the relevant issue numbers?

Render coverage badge using latest successful pipeline

## What does this MR do?

This MR make test coverage badge to report value for the latest successful pipeline, instead of the latest one, regardless the status.

Latest pipeline is often running, which makes coverage report inaccurate. Latest pipeline can be also the failed one, which may mean that not all stages got processed, therefore coverage report can be inaccurate as well.

This also improves coverage badge performance because it is not necessary to touch repository to get recent SHA on the branch.

## Why was this MR needed?

See #21013

## What are the relevant issue numbers?

Closes #21013
