test_namespace.py::test_aliases fails due to Plotly template in namespace

[SpandanBhoiIITM]

Describe the bug

While running the test suite locally using pytest, the test
tests/test_namespace.py::test_aliases fails.

The failure happens because Plotly templates exposed in the arviz
namespace (for example arviz_cetrino_template) originate from
plotly.graph_objs.layout._template instead of the arviz package.

Example:

import arviz as az
az.arviz_cetrino_template.module
'plotly.graph_objs.layout._template'

The test checks:
assert orig_lib.startswith("arviz")

so the assertion fails.

Possible solution could be excluding these template objects in the
test_aliases check similar to how from_netcdf and from_zarr
are handled.

Environment:
Python 3.12
pytest 9.0.2
ArviZ 1.0.0

Hi! I'm new to contributing to ArviZ and would like to work on this issue.
From the description, it looks like the test is failing because some Plotly template objects are being exposed in the ArviZ namespace. I will try to reproduce the issue locally and see if excluding those templates from the test_aliases check fixes the problem.
Please let me know if it's okay for me to work on this.
