Fix LaTeX ColorV2 Extension - Greg Bernhardt

[pbuk]

@Greg Bernhardt: the $\LaTeX$ color extension doesn't seem to be working. MathJax is downloading the colorv2 extension but in check-for-tex.js you have

autoload: {
  color: [],
  colorV2: ['color'],
}

I'm not sure if this will fix it* but I think it shoud be

autoload: {
  color: [],
  colorv2: ['color'],
}

(note the lower case "v" in line 3).

* Edit: experiments elsewhere indicate that this will fix it.

* Edit2: you could of course delete both the color and colorv2 keys to use the 'proper' MathJax V3 color module which works the same way $\TeX$ does, but this would break colors in old posts under MathJax V2 (if there are any).

$\color{red}{x} + \color{blue}{y}$

$\color{red}{x} + \color{blue}{y}$

I'm still getting the old https://www.physicsforums.com/check-for-tex.js file with colorV2:

(function(){var body=document.body.textContent;if(body.match(/(\$\$|##|\[tex\]|\[itex\])/)){if(!window.MathJax){window.MathJax={loader:{load:["ui/lazy"],source:{"ui/lazy":"https://www.physicsforums.com/insights/lazy.js"}},tex:{inlineMath:[["[itex]","[/itex]"],["##","##"]],displayMath:[["[tex]","[/tex]"],["$$","$$"]],processEscapes:true,macros:{href:"{}"},tags:"ams",autoload:{color:[],colorV2:["color"]}},options:{skipHtmlTags:["script","noscript","style","textarea","pre","code"],ignoreHtmlClass:"tex2jax_ignore|dno",processHtmlClass:"tex2jax_process"}};}
var script=document.createElement("script");script.src="https://cdn.jsdelivr.net/npm/mathjax@3/es5/tex-chtml.js";script.async=true;document.head.appendChild(script);}})();

even after a force refresh - may need a cache invalidation?

Incidentally the problem seems to be of MathJax's creation, see the documentation for the current release: http://docs.mathjax.org/en/latest/input/tex/extensions/colorv2.html vs 3.0: https://docs.mathjax.org/en/v3.0-latest/input/tex/extensions/colorV2.html.
