Update our browserslist config per "Best Practices"

[bradenmacdonald]

Our browserslist config is currently not following the Best Practices that the browserslist project recommends.

In particular, they say:

Don’t remove browsers just because you don’t know them. Opera Mini has 100 million users in Africa and it is more popular in the global market than Microsoft Edge. Chinese QQ Browsers has more market share than Firefox and desktop Safari combined.

Here is the list of supported browsers (from npm run supported), before and after this change:

I don't have a strong opinion on this change, but I do think it makes sense to follow the best practices if there's little or no cost to doing so.
