What

nbr() documents its second band as swir_agg in the docstring, but the signature parameter is swir2_agg. This renames the docstring entry to match.

Why

Copy the parameter name straight out of the rendered docs and nbr(..., swir_agg=...) raises a TypeError. Every other function in the module documents its parameters under the real names, so nbr was the odd one out.

Tests

Adds test_docstring_params_match_signature, parametrized over the 17 public index functions, asserting the documented parameter set equals the signature parameter set. It fails on the pre-fix docstring and passes after the rename. Full multispectral suite (171 tests across numpy, dask, and cupy) passes.

Docs-only change, no API impact, no deprecation needed.

Closes #3433

nbr() documents its second band as swir_agg, but the signature parameter
is swir2_agg, so copying the name from the docs raises a TypeError. Rename
the docstring entry to swir2_agg.

Add test_docstring_params_match_signature over the 17 public index
functions to assert the documented parameter set matches the signature.
