Add the comprehensive error message style from `fig.update_traces` to `fig.update`

[joelostblom]

When I specify a parameter that does not exist to the update_traces method of a figure object, I get a comprehensive error message, which is excellent for troubleshooting and parameter discovery:

import plotly.express as px

iris = px.data.iris()
fig = px.scatter(iris, 'sepal_width', 'sepal_length', 'sepal_length')
fig.update_traces(test='asdf')

ValueError: Invalid property specified for object of type plotly.graph_objs.Scatter: 'testaa'

    Valid properties:
        cliponaxis
            Determines whether or not markers and text nodes are
            clipped about the subplot axes. To show markers and
            text nodes above axis lines and tick labels, make sure
            to set `xaxis.layer` and `yaxis.layer` to *below
            traces*.
        connectgaps
            Determines whether or not gaps (i.e. {nan} or missing
            values) in the provided data arrays are connected.
        customdata
            Assigns extra data each datum. This may be useful when
            listening to hover, click and selection events. Note
            that, "scatter" traces also appends customdata items in
            the markers DOM elements
        customdatasrc
            Sets the source reference on plot.ly for  customdata .
        ...

When I try the same thing with the update method of a figure object, the error message is less useful.

import plotly.express as px

iris = px.data.iris()
fig = px.scatter(iris, 'sepal_width', 'sepal_length', 'sepal_length')
fig.update(test='asdf')

KeyError: 'test'

Particularly for these methods where the docstring cannot include an explanation of all the **kwargs parameters, it is highly useful to have the detailed error message and it would be great if it was possible to include it for the update figure method.

That is pretty weird, given that magic-underscores do work for assignment i.e. fig.update(layout_title_text='Hello, Figure') works although fig.update(layout_title_test='Hello, Figure') doesn't raise the same error as fig.update_layout(title_test='Hello, Figure')

@jonmmease is this an easy add?

Hi - we are trying to tidy up the stale issues and PRs in Plotly's public repositories so that we can focus on things that are still important to our community. Since this one has been sitting for several years, I'm going to close it; if it is still a concern, please add a comment letting us know what recent version of our software you've checked it with so that I can reopen it and add it to our backlog. Thanks for your help - @gvwilson
