Align `dpnp.tensor.expand_dims` with Python array API 2025.12 (#2988)

This PR aligns `dpnp.tensor.expand_dims` with the Python array API
specification (revision 2025.12), which defines the signature as
`expand_dims(x, /, axis)` — `axis` is a **required**
positional-or-keyword argument with no default.

Previously the tensor-level function used `expand_dims(X, /, *, axis=0)`
(`axis` keyword-only with a default of `0`), which did not match the
standard.
The public `dpnp.expand_dims` wrapper is also made positional-only for
its array argument (`(a, /, axis)`), consistent with sibling array-API
functions in the same module (`squeeze`, `reshape`, `broadcast_to`,
`stack`).

The function body was already multi-axis capable; this change updates
the signature and documentation to match, and closes gaps in test
coverage.
