### Motivation and context
This is a very simple pull request. The type of the credentials
parameter of `make_client` is currently `Optional[Tuple[int, int]]`, but
it should be `Optional[Tuple[str, str]]` as used by `Client#login`. This
PR makes that change.
### How has this been tested?
The typing does not affect the functionality of the code (just the
warnings I get in an IDE).
- Added auth docs in API schema and SDK ApiClient/Config (fixes#1517)
- Added SDK docs with API, SDK and CLI docs
- Added `develop` branch in the docs
- Allowed unauthorized access to `api/docs`, `api/swagger`, `api/schema` endpoints
- Added `--insecure` env var to control host checks in CLI
- Refactored `build_docs.py` (backported https://github.com/openvinotoolkit/datumaro/pull/589)
- Extracted requirements file for site
