uppy: remove legacy bundle

IE11 is long dead, Uppy doesn't use any web API that is not already supported by every major browsers, maintaining the legacy bundle is more work than it's worth, let's get rid of it!

 ## Browser Support
 
-We aim to support recent versions of Chrome, Firefox, Safari and Edge.
-
-We still provide a bundle which should work on IE11, but we are not running tests on it.
-
-### Polyfills
-
-Here’s a list of polyfills you’ll need to include to make Uppy work in older browsers, such as IE11:
-
-* [abortcontroller-polyfill](https://github.com/mo/abortcontroller-polyfill)
-* [core-js](https://github.com/zloirock/core-js)
-* [md-gum-polyfill](https://github.com/mozdevs/mediaDevices-getUserMedia-polyfill)
-* [resize-observer-polyfill](https://github.com/que-etc/resize-observer-polyfill)
-* [whatwg-fetch](https://github.com/github/fetch)
-
-If you’re using a bundler, you need to import them before Uppy:
-
-```js
-import 'core-js'
-import 'whatwg-fetch'
-import 'abortcontroller-polyfill/dist/polyfill-patch-fetch'
-// Order matters: AbortController needs fetch which needs Promise (provided by core-js).
-
-import 'md-gum-polyfill'
-import ResizeObserver from 'resize-observer-polyfill'
-
-window.ResizeObserver ??= ResizeObserver
-
-export { default } from '@uppy/core'
-export * from '@uppy/core'
-```
-
-If you’re using Uppy from CDN, those polyfills are already included in the legacy
-bundle, so no need to include anything additionally:
-
-```html
-<script src="https://releases.transloadit.com/uppy/v3.21.0/uppy.legacy.min.js"></script>
-```
+We aim to support recent versions of Chrome, Firefox, and Safari.
