Prevent :move overwriting destination & Add :move! to force overwrite

[5-pebbles]

If you run the old :move command with a path that already exists, that file will be overwritten without warning.

Example:

echo "hello world" > a
echo "bye world" > b

hx b
# the run: `:move a`

cat a
# output: bye world

In this PR moving to an existing destination will display the following: Destination exists. Use `:move!` to overwrite.

I have also added the :move! command which behaves the same as the old move, overwriting the destination.

I finally tried to look into this, and I can't reproduce the github actions error.

I don't understand what the problem is... 5-pebbles#3 it works fine on my fork.
I assume it has something to do with caching, but I will look into github actions further this week.

master might've been broken when you last merged with it. You can merge with master again and see if that fixes the CI

Um, I did not think that was the issue... Thank you very much for pointing that out!
