DateSlider step parameter is not in ms

[rgr-1]

ALL software version info

panel: 1.5.1 (and 1.5.0)
bokeh: 3.5.2 (and 3.6.0)

Description of expected behavior

https://panel.holoviz.org/reference/widgets/DateSlider.html

• step (number): The selected step i the slider in milliseconds

Observed:

step is in days. I.e. step=1 adjusts slider in 1 day increment.

In addition:

• on your page above I can make 1 hour increment by specifying step = 1/(24). Please see attached. This would be absolutely acceptable..
• however in my project it fails with bokeh (rightfully?) expecting integer for step parameter.

  File "~/miniconda3/envs/my/lib/python3.12/site-packages/bokeh/core/property/bases.py", line 363, in prepare_value
    raise ValueError(f"failed to validate {obj_repr}.{name}: {error}")
ValueError: failed to validate DateSlider(id='9e019eed-0b4d-4faa-bb5e-aee6fca643ba', ...).step: expected a value of type Integral, got 0.041666667 of type float

Bokeh changed it from milliseconds to days at some point. I have opened a PR to clarify this.

It does not look like Bokeh has a DatetimeSlider.
