fix(deps): relax bokeh upper pin, update custom TS usage

[gforsyth]

Trying to relax the upper pin for bokeh to see what happens in CI.

We currently pin bokeh to >3.1,<=3.6 in dependencies.yaml but not in the rattler-build recipe, so we are testing a different dependency set than the one that a user will get if they install using conda.

Fixes #728

I fixed and updated some docstring formatting because I thought warnings were getting escalated to errors -- the actual issue was in some stricter Typescript types in newer version of Bokeh.

That was fixed by removing the CustomInspectTool alias and just using the instance directly.

I can rip out the docstring fixes if we want to keep this PR more tightly scoped.

Thanks Gil! 🙏

Fixed one conflict related to file header changes from PR: #734

Though noticed there are a few more places we likely want these changes

cc @KyleFromNVIDIA (to check we are capturing these correctly)

Kyle submitted PR ( #736 ) for the SPDX changes

Have tried to resolve the conflicts it introduced with this PR

Looks like that captures the header changes that were originally being made here

Though please double check and make sure this looks ok

[KyleFromNVIDIA]

My PR based its headers off of git log, which in some cases revealed start years other than 2019, such as 2020 and 2023. But this PR had them all at 2019. Which one is correct?

CI passing for the changes made in this PR is just api level confirmation. We still need some confirmation that the dashboards work in notebooks and colab, has that been tried @gforsyth ?

[gforsyth]

No, I haven't checked that -- probably better if someone familiar with the package takes a look so they can verify the outputs.
