chore: revert adjust browserslist to compile optional chaining

[nwidynski]

This reverts #2860 to reduce bundle sizes and improve runtime performance. This change was originally scheduled for July 2022 so this should not come unexpected by now 😅

Noteworthy: Chrome 85+ addressed scrollLeft RTL compatibility issues, currently normalized by our virtualization utils, but simultaneously introduced new direction issues with scrollTop 🫠

We'll need to make sure that this isn't still the case #8384 (comment)
as well as making sure this still works #7137

I can make a PR to turn on our verdaccio based fake "prod" build soon

@snowystinger I linked Devons original comment for the planned deprecation date of Webpack 4 (July 2022). Has this been extended in the meantime?

Yeah, I noticed that link after I posted, thanks for that.

Unfortunately it's not about deprecation of webpack 4, it's about usage. A brief glance at https://www.npmjs.com/package/webpack/v/5.102.1?activeTab=versions would seem to indicate that the usage of webpack 5 has grown a lot.

Could probably add up the downloads across the major versions to get a statistic.

Somewhat specifically, we'll have to check inside Adobe as well...
