Only expose 1 diff style in diffs endpoint

See merge request gitlab-org/gitlab!19317

When enabling the `single_mr_diff_view` feature flag, the backend will
only render one kind of diff: inline or parallel. The feature is
disabled for now until the frontend has been updated.

To switch the view, the frontend can pass a `view` param containing
either `inline` or `parallel`. That will get written to a cookie. The
response for diff files will then contain either
`highlighted_diff_lines` or `parallel_diff_lines` but no longer both.

Update omniauth_openid_connect to v0.3.3

See merge request gitlab-org/gitlab!19525

During a project migration to another shard in
https://gitlab.com/gitlab-com/gl-infra/production/issues/1250, we
noticed the GetAllLFSPointers RPC was timing out for a repository
that was marked as read-only.

To avoid updates while the migration is happening, we need to check
the `repository_read_only` flag and skip the update.

Some OpenID servers are configured to format the request to the client
application as a POST request (form_post). This version of the gem
allows you to actually use an unused configuration option.
