Lexical version: v0.34.0

Steps To Reproduce

1. Write a right-to-left paragraph.
2. Insert some decorator node, e.g. a date node.
3. Try to move the cursor from the start to the end or vice versa.

The current behavior

When the decorator node is selected and the right/left arrow key is pressed, the selection is always moved before/after.

The expected behavior

If the paragraph is RTL and the right arrow key is pressed, the selection should move before instead of after, and the same being said for the left arrow key.

Impact of fix

RTL users.
