Support pasting URLs over selection text in the textarea editor. Does
not work in EasyMDE and I don't intend to support it. Image paste works
as usual in both Textarea and EasyMDE.
The new `replaceTextareaSelection` function changes textarea content via
[`insertText`](https://developer.mozilla.org/en-US/docs/Web/API/Document/execCommand#using_inserttext)
command, which preserves history, e.g. `CTRL-Z` works and is also
demostrated below. We should later refactor the image paste code to use
the same function because it currently destroys history.
Overriding the formatting via `Shift` key is supported as well, e.g.
`Ctrl+Shift+V` will insert the URL as-is, like on GitHub.

WIP because:
- [x] Some calls set a `content-type` but send no body, can likely
remove the header
- [x] Need to check whether `charset=utf-8` has any significance on the
webauthn calls, I assume not as it is the default for json content.
- [x] Maybe `no-restricted-globals` is better for eslint, but will
require a lot of duplication in the yaml or moving eslint config to a
`.js` extension.
- [x] Maybe export `request` as `fetch`, shadowing the global.
Since we are using EasyMDE now, we do not need to keep the SimpleMDE code anymore.
This PR removes all legacy SimpleMDE code, and makes some related changes:
* `createCommentEasyMDE` can accept native DOM element, and it doesn't need `jQuery.data` to store EasyMDE editor object (as discussed about the frontend guideline).
* introduce `getAttachedEasyMDE` to get the attached EasyMDE editor object, it's easier to find all the usage of EasyMDE.
* rename variable names from `$simplemde` to `easyMDE`, the `$` was incorrect because it is a EasyMDE editor, not a jQuery object.
With this PR, it will be easier to do more refactoring or replacing EasyMDE with other editors.
* Add new JS linter rules
Adds a few useful rules from eslint-plugin-github. Notable changes:
- Forbid dataset usage, its camel-casing behaviour makes it hard to
grep for attributes.
- Forbid .then() and .catch(), we should generally prefer await for new
code. For rare cases where they are useful, a eslint-disable-line
directive can be set.
- Add docs js to linting
* also enable github/array-foreach
* small tweak

* Remove appSubUrl from pasted images
Since we fixed the url base for the links in repositories we no longer need to add
the appsuburl to pasted image links.
