Running the GitHub Action for [`mypy`](https://github.com/pydata/xarray/blob/main/.github/workflows/ci-additional.yaml#L121) locally returned errors: ```bash $ python -m mypy --install-types --non-interactive xarray/core/merge.py:43: error: ""tuple"" is not subscriptable [misc] xarray/core/merge.py:44: error: ""tuple"" is not subscriptable [misc] xarray/core/merge.py:45: error: ""tuple"" is not subscriptable [misc] xarray/backends/api.py:62: error: ""dict"" is not subscriptable [misc] Found 4 errors in 2 files (checked 144 source files) ``` ### What did you expect to happen? No type errors from `mypy`. ### Minimal Complete Verifiable Example _No response_ ### MVCE confirmation - [X] Minimal example — the example is as focused as reasonably possible to demonstrate the underlying issue in xarray. - [X] Complete example — the example is self-contained, including all data and the text of any traceback. - [X] Verifiable example — the example copy & pastes into an IPython prompt or [Binder notebook](https://mybinder.org/v2/gh/pydata/xarray/main?urlpath=lab/tree/doc/examples/blank_template.ipynb), returning the result. - [X] New issue — a search of GitHub Issues suggests this is not a duplicate. ### Relevant log output _No response_ ### Anything else we need to know? _No response_ ### Environment
