Adding confirmation message on save

[premell]

When saving there is no confirmation that it actually succeeded:
Helix:

nvim:

PS: This is such a small thing that I wasnt sure if I should even make an issue. However it might be a good issue, also there might be more places where messages would be nice

I ran into this a while back, was confused when I tried saving a read-only file. Everything looked good (or at least the same), there was no error (which probably deserves a separate issue) but it was confusing when I checked git status and found no modifications.

I only learned that I had no write permissions when I tried making the same edit in vim and saw the error on save.
