[Suggestion] upgrade guide from version 9.x to 10.x dist/esm folder

[thomasneger]

Hi @wojtekmaj, thank you so much for this library. I was just migrating our code base from v9 to v10 and ran into a 404 on the AnnotationLayer.css and TextLayer.css files for an esm build.

Previously, they were located in the dist/esm folder, now it's just dist. I think it would be nice to leave a trace in the migration notes https://github.com/wojtekmaj/react-pdf/wiki/Upgrade-guide-from-version-9.x-to-10.x that the path has changed.

Maybe something like:

In case you were using support for annotations or text layer, update the paths as so:

- import 'react-pdf/dist/esm/Page/AnnotationLayer.css';
- import 'react-pdf/dist/esm/Page/TextLayer.css';
+ import 'react-pdf/dist/Page/AnnotationLayer.css';
+ import 'react-pdf/dist/Page/TextLayer.css';

Hope this helps someone else. Best.
