Use "browser" tag in package.json

[ryanlsimms]

Bootstrap imports popper using import * as Popper from '@popperjs/core', which will aways import the cjs version, even if the distribution is intended for browser. This fails in my semi-buildless workflow when importing bootstrap using rollupjs.

Some of workarounds given in #933 work, but I think the best solution would be to use the "browser" field in package.json as intended and point it to the umd (or esm?) distribution.

"main": "dist/cjs/popper.js",
"main:umd": "dist/umd/popper.js",
"module": "lib/index.js",
"unpkg": "dist/umd/popper.min.js",
"browser": "dist/umd/popper.js",

browser is not supposed to be umd. It can be a map to specify which files need to be aliased to make package work in browser. There is no need for it in this project.

At this point in time we are not updating Popper's build setup. For Floating UI we're working on low/no build compatibility here #1502
