Feature: Merging two identical links into one node

[levensta]

Description

In lexical, it is possible for two LinkNodes with identical URLs to be adjacent to each other. This situation can be reproduced manually: insert a TextNode or ElementNode that will split the link into two nodes, and then delete the inserted element.

Impact

It would be effective to merge the contents of adjacent links into a single node, as there is no compelling reason to maintain different nodes that lead to the same URL and do not contain any other content between them.

In this we can try a solution that whenever the user tries to paste any content within the link path name then that content should get attached to the text part inside the link rather than creating a new text section which seperates the 2 links part which indeed makes 2 links having same url .

I don't think you need to worry about paste specifically, you can use a transform on LinkNode to do this normalization. Would make sense to add this after #8158
