💥Offline update doc conflict

[AntoLC]

Problem

2 users are editing the same doc, 1 is offline, when the offline user get the connection back , he can override the the work of the first user.

Solution ?

Add at least a warning to say that the update is overriding the document. Warning could be on the version ?

Could be nice to have a modal proposing the 2 choices:

• Override - as it is now, we override the existing doc
• Or Rebase - we pull the updated doc and merge it with offline updated Doc (see y.js)
