This allows adding a dimension of an array. Which is relevant when for example using keepdims in NamedArray.reduce.

Normally you can do this with None but that's not really allowed in the getitem documentation currently https://data-apis.org/array-api/2022.12/API_specification/generated/array_api.array.getitem.html

Should follow the standard but with an additional dim argument, dim should be preferred over the axis argument. https://data-apis.org/array-api/draft/API_specification/generated/array_api.expand_dims.html
