Make namespace owner master of project upon creation

Closes #29446

See merge request !10910

- We upgraded `rugged` to 0.25.1.1 in !10286 for %9.1

- Prior to this upgrade, the default sort order for commits returned by
  `Gitlab::Git::Repository#find_commits` was `Rugged::SORT_DATE`, which the
  graph relied on.

- While upgrading `rugged`, the MR also changed this default to
  `Rugged::SORT_NONE`, which broke commit ordering in the graph.

- This commit adds an option to `Gitlab::Git::Repository#find_commits` to sort
  by date, and changes the graph builder `Network::Graph` so it explictly
  requests the `:date` sort order

Remove view fragment caching for project READMEs

Allow admins to sudo to blocked users

See merge request !10842

When an admin creates a project in the namespace of a user, that user
automatically gains master access to that project.

The `MarkupHelper#markup` method does everything we need here.

Because the post-processing of the rendered README is dependent on the
context (i.e. the current user), do the post-processing when the
README is being displayed.

It does more than solely GitLab Markdown, so rename to MarkupHelper.

Triple backticks aren't allowed inside <details> elements, so add an explicit
<pre> instead.
