This commit vendors the omniauth-gem v4.0.0 to support:

1. OmniAuth v1 and v2. OmniAuth v2 disables GET requests by default
   and defaults to POST. GitLab already has patched v1 to use POST,
   but other dependencies need to be updated:
   https://gitlab.com/gitlab-org/gitlab/-/issues/30073.

2. [`oauth2`](https://github.com/oauth-xx/oauth2) v1.4.9 and up.
   [v1.4.9 fixed relative URL
   handling](https://github.com/oauth-xx/oauth2/pull/469).

   However, this breaks the default GitLab.com configuration and
   existing configurations that use the `/api/v4` suffix in the `site`
   parameter.

   [omniauth-gitlab v4.0.0 fixed the first
   issue](https://github.com/linchus/omniauth-gitlab/pull/22), but the
   second issue requires an admin to update `site` to drop the suffix.

   This fork restores backwards compatibility that was removed in
   omniauth-gitlab v2.0.0.

Add ability to edit work items weight widget

See merge request gitlab-org/gitlab!90044

The weight widget updates are only persisted in the frontend Apollo
Cache for now. When the backend mutation for updating the weight has been
created, the weight widget will be updated again to use this mutation.

Because we create a `Date` Object and pass it to the frontend, the end
date of the trial is shown in the browser's timezone.
However, we store the end date in UTC and also show the end date in UTC
on the billing page. To streamline the dates, this MR changes the
formatted date in the trial popover to be in UTC as well.

Changelog: fixed
EE: True

Fix issue list for closed issues without closed_at

See merge request gitlab-org/gitlab!91442

Ipynb diffs would still be generated when the file was collpsed, which

Changelog: fixed

Remove JSON format for epics index page

See merge request gitlab-org/gitlab!89490

Avatars started displaying as block elements after they were
updated with `display: flow-root`. This created a BFC which
we wanted in order to contain the floated avatars. However,
this makes the element a block. We can make the element
inline instead with a BFC with `display: inline-block`.

Changelog: fixed
