The version above 4.21 of browserslist does not include IE by default and it causes error

[edwardfxiao]

Recently browserslist removed IE 11 from defaults in 4.21, which causes var _browserslist = require("browserslist") in caniuse-api does not include IE by default at all.

Therefore versions['ie'] is undefined, and versions['ie'].x reports error.

The older version of browserslist contains ie

if (versions[browser].x >= browserList[browser]) {

//TypeError: Cannot read properties of undefined (reading 'x')

// console.log(versions) ->
