Fix the function name in the get_minimal_required_cuda_ver_from_ptx_ver examples

[LeSingh1]

The Examples section of get_minimal_required_cuda_ver_from_ptx_ver() calls a function
that does not exist:

    Examples
    --------
    >>> get_minimal_required_driver_ver_from_ptx_ver("8.8")
    12090
    >>> get_minimal_required_driver_ver_from_ptx_ver("7.0")
    11000

get_minimal_required_**driver**_ver_from_ptx_ver appears nowhere else in the repo — I
grepped every .py, .pyx, .rst and .md; these two lines are the only hits. The
export in cuda/bindings/utils/__init__.py, the test in tests/test_utils.py,
docs/source/module/utils.rst and both release-notes files all use the ..._cuda_ver_...
spelling. It is a rename that missed its own docstring.

These are doctests, and autodoc renders this docstring into the public API docs, so users
are shown two calls that raise:

NameError: name 'get_minimal_required_driver_ver_from_ptx_ver' is not defined.
Did you mean: 'get_minimal_required_cuda_ver_from_ptx_ver'?

Nothing caught it because pytest is not run with --doctest-modules
(cuda_bindings/pyproject.toml sets addopts = "--benchmark-disable --showlocals").

Test

test_ptx_utils_docstring_examples runs doctest.testmod() over the module, next to the
existing test_ptx_utils. It reports 2 failures on main and 0 with this change, and
needs no GPU and no toolkit — _ptx_utils imports only re. It also covers the
get_ptx_ver example, which is correct today and now stays that way.

I scoped the test to this one module rather than turning on --doctest-modules repo-wide;
that is a bigger decision and would pull in the Cython modules' docstrings too.

Note: #2541 and #2551 also touch cuda_bindings/tests/test_utils.py — at the end of the
file and around line 117 respectively. This one lands next to test_ptx_utils near the
top, so the three are independent. Happy to rebase whichever lands last.
