Summary: (@kevinbarabash) This diff extracts MathML builder tests out into a separate file and updates them to use jest snapshot testing. It updates the output of prime ' from using identifier nodes <mi> to operator nodes <mo>. It also updates large operators with limits to use munderover instead of msupsub. I added an option to remove unnecessary mrows to buildGroup. Right now it's only used for by groupTypes.supsub. I'll see if it can be used elsewhere (everywhere?) in a follow up PR. Test Plan: - make test w/o errors - verify mathml snapshots contain the desired markup
