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.

`git log --follow` is only supported for a single path. CE doesn't currently
pass multiple paths, but EE does.

FFaker can generate data that randomly break our test suite. This
simplifies our factories and use sequences which are more predictive.

- Migration in Repository#is_ancestor?

`Kaminari.paginate_array` takes some options, most relevant of which is
a `total_count` parameter. Using the `commit_count` for `total_count`
lets us correctly treat the return of `Repository#commits` as a subset
of all the commits we may wish to list.

Addition of a new `Repository#commit_count_for_ref` method was
necessarry to allow the user to start from an arbitrary ref.

This reverts commit cb10b725c8929b8b4460f89c9d96c773af39ba6b.

Backport changes from the EE-only squash implementation, which would
otherwise conflict when merge CE into EE.

<https://gitlab.com/gitlab-org/gitlab-ee/merge_requests/1024>

In repositories such as https://github.com/git/git.git, annotated tags can
point to blobs, not necessarily to commits. `Repository` attempts to
return the tags in the order of the commit date, but if a commit is not
available the previous implementation would error due to a `nil` target.
This change modifies the code to use the current time if a commit
is not associated with the given tag.

Closes #27228
