Add bokeh 3.8.1 (python).

[bfonta]

Adding the data visualization python package bokeh. It's particularly useful to build interactive dashboards or event displays.
I've updated the dependencies based on what the latest 3.8.1 version requires:

(Bokeh) bfonta@tp16:~  $ pip3 show bokeh
Name: bokeh
Version: 3.8.1
Summary: Interactive plots and applications in the browser from Python
Home-page: https://bokeh.org
...
Requires: contourpy, Jinja2, narwhals, numpy, packaging, pandas, pillow, PyYAML, tornado, xyzservices
Required-by: 

P.S.: It's not clear why the bokeh.file already existed; seems to have been first introduced here as py2-bokeh.spec.

Hi @bfonta we have bokeh version 3.8.0, but ig it's not being built due to it needing Python version 3.10. If I correctly remember.

[akritkbehera]

We also need PyYAML which needs Python to be >3.10

@makortel kinded pointed me to the current transition to python 3.12. Should this PR be merged once the python version is updated?

[smuzaffar]

@bfonta , Requires: should have space separate list of package so please remove the , from the above line.
py3-xyzservices and py3-narwhals are new packages which are not part of our distribution so you need to add these to requirements.txt file along with their xyzservices.file and narwhals.file for proper dependencies.

[bfonta]

1. Commas removed.

2. pip show tells me neither has dependencies. Should I nevertheless add "empty" files:

Requires:

?

[smuzaffar]

if these new packages do not have any dependency then just adding these in the requirement.txt file is enough e..g

narwhals==2.13.0
xyzservices==2025.11.0

[bfonta]

Done.

P.S.:
From the xyz-services docs:

The package does not depend on any other apart from those built-in in Python.

And the narwhals docs also mention no required dependencies are needed.

@bfonta , though narwhals has no runtime deps but it requires hatchling for building. Can you please add a new file cmsdist/pip/narwhals.file with the following contents

BuildRequires: py3-hatchling
