Blocknote editor fix (#11823)

After reading the blocknote documentation :

- we decided to increase to 100% the lines width
- we decided to reduce as much as possible inner padding
- we decided it's on the parent to decide the padding of the richtext
The two last points are recommended in a discussion on the project
blocknote. This way clicking on padding won't trigger weird behaviour on
Chrome.
