When using the end of line motion ($) while in temporary mode, the
cursor would be placed in insert mode just before the last character
instead of after, just like in NeoVim.
This happens because `EndOfLine` kind of assumes that we're in `Normal`
mode and simply places the cursor in the last character instead of the
newline character.
This commit moves the cursor one position to the right when exiting
temporary mode and the motion used was `Motion::EndOfLine`
- Update `vim::normal::Vim.exit_temporary_normal` to now accept a
`Option<&Motion>` argument, in case callers want this new logic to
potentially be applied
Closes#42278
Release Notes:
- Fixed temporary mode exit when using `$` to move to the end of the
line
