Add denote-slug-remove-accents function
This is based on the code originally written by Jean-Philippe Gagné
Guay in issue 603: <https://github.com/protesilaos/denote/issues/603#issuecomment-2869702877>.
I made stylistic changes to it to make it fit with the rest of denote.el.

I am adding this in response to issue 603 and 718:

- <https://github.com/protesilaos/denote/issues/603> with
  participation from Davi Ramos and Jean-Philippe Gagné Guay;
- <https://github.com/protesilaos/denote/issues/718> with
  participation from o-rxw and Alan Schmitt.

In implementing this, I am changing my mind that this is purely a
documentation issue. I realised it is better for us to have the main
function in denote.el, so that we can test it better.
