Add YankEndOfLine action (#39143)

Since 2021 Neovim remaps Y to $y (1). DO the same in zed through a new action `YankToEndOfLine`. 

1: https://github.com/neovim/neovim/pull/13268

Release Notes:

- Added vim::YankToEndOfLine action which copies from the cursor to the end of the line excluding the newline. We bind it to Y by default in the vim keymap.
