Downgrade nanoid from v3 to v2 for IE11 support

This pull request will downgrade nanoid from v3 to v2 because nanoid v3 doesn't support IE11.

Alternative solution

At first, I tried to allow the both versions, v2 and v3, with the following patch.

diff --git a/src/state/editor.js b/src/state/editor.js

Probably It works well (I didn't test it enough), but I got a warning from webpack that is used in my project.

WARNING in ./node_modules/prosemirror-dev-tools/dist/esm/utils/nanoid.js 3:17-30
"export 'default' (imported as 'nanoidDefault') was not found in 'nanoid'

And I think this solution is tricky, so I just downgraded nanoid to v2.
