feat: add logging to file

[Robitx]

@teto happy?

[teto]

I will try to run this to test it

@teto logging logic works fine on my end, will merge and go to sleep

tail -f ~/.local/state/nvim/gp.nvim.log

I see twice the same message which is strange ?

@teto that's weird, do you see it twice in _log_history when you check :GpInspectPlugin?

[teto]

no. Hum that might be due to how I initialize gp.nvim so forget about it. I want to get rid of the setup function (at least make the plugin usable without it). See https://mrcjkb.dev/posts/2023-08-22-setup.html for reasons.
