Mosaic 2x2 table parameter selection frontend update

[danicahelb]

Hey @jernestmyers this slipped through the cracks, and is fine to fix for b63.

The heading for the facet parameter selector should be Stratification variable (see https://www.figma.com/file/Su1eNm3Bby85CfrnX42L7q/2x2-table-UI?node-id=44%3A169&t=aGyO1qjiYDRcMRLJ-0)

Instead, it says 2x2 variables

Ah, bummer. I can probably open the PR tonight if we'd like to get it into b62.

@jernestmyers if that is possible that would be awesome. I don't want to screw up @dmfalke's plans though...

[jernestmyers]

Yeah, I pushed a fix and tagged him for the PR. I'll let him determine if it's worth the hassle. Sorry for the bug 😩

[danicahelb]
