`Mathjax.Hub.config` used for plotly 5.7.0

[AakashGfude]

Could not find a duplicate of this issue anywhere so, not sure if anyone else had an issue like this, but when using plotly in a sphinx project and creating HTML pages, I get the following js code included in my HTML page:

<div class="output text_html">        <script type="text/javascript">
        window.PlotlyConfig = {MathJaxConfig: 'local'};
        if (window.MathJax) {MathJax.Hub.Config({SVG: {font: "STIX-Web"}});}
        if (typeof require !== 'undefined') {
        require.undef("plotly");
        define('plotly', function(require, exports, module) {
            /**
* plotly.js v2.11.1
.....

When I have a math block in the same page as a plotly graph, then window.MathJax is defined and MathJax.Hub.Config gets called. Which throws an error as I am using mathjax v3, which is supported by v5.7.0.

The line MathJax.Hub.Config({SVG: {font: "STIX-Web"}}) I see written in a bunch of files like:
https://github.com/plotly/plotly.py/blob/master/packages/python/plotly/plotly/io/_base_renderers.py#L240

Is it a legit issue?

@alexcjohnson @archmoj can you take a look plz?

You must check the version of MathJax to be v2 e.g. here

if (window.MathJax && (window.MathJax.version || '').split('.')[0] === '2') {MathJax.Hub.Config({SVG: {font: "STIX-Web"}});}

@archmoj let's add this to the queue for after the coming plotly.js release, see if you can figure out the equivalent command to switch to when we detect v3.

@AakashGfude thanks for the report!
