Fix name in the API error tracking spec

See merge request gitlab-org/gitlab!26022

In https://gitlab.com/gitlab-org/gitlab/-/merge_requests/25936
we align the return code for the same error to be 403.

Nevertheless, it seems the internal API needs it to be
401, otherwise, the custom error message won't be shown.

Use Workhorse acceleration on Project Import file upload

See merge request gitlab-org/gitlab!25361

This is related to API endpoints only, UI endpoints
(Import::GitlabProjectsController) will be accelerated
in the next, separate MR.
Since we are touching an existing API, we should deploy it gradually.
So this MR will support both accelerated and "vanilla"
uploads for the endpoint.
