Adding full Italian translation of fish shell, by a native Italian speaker.

• I solemnly swear that this is all original content of which I am the original author
• Pull request title is prepended with [language/lang-code] (example [python/fr-fr] or [java/en])
• Pull request touches only one file (or a set of logically related files with similar changes made)
• Content changes are aimed at intermediate to experienced programmers (this is a poor format for explaining fundamental programming concepts)
• If you've changed any part of the YAML Frontmatter, make sure it is formatted according to CONTRIBUTING.md
  • Yes, I have double-checked quotes and field names!

These parts of the text should be re-written to something normal in the English text first, then re-translated to Italian:

fish is better than bash
sick egg, nadia. no u do really goofy shit.
It's very late I should not waste my time with this
Nobody heard you
install Gentoo
I use arch btw

What do you mean? meaning the this phrases aren't appropriate for the context?

yea

[mariostabile1]

yea

I wrote down some substitutions for the not appropriate phrases, with some different italian sentences (not correlated with the english doc for fish)

Substitutions are:

fish is better than bash -> Questo testo sarà stampato sul terminale = This text will be printed on the terminal
sick egg, nadia. no u do really goofy shit. -> Qui cisarà un testo = Here there'll be some text
It's very late I should not waste my time with this -> Testo testo, bla bla bla = Text text, blah blah
Nobody heard you -> Altro testo, bla bla = More text, blah blah
install Gentoo -> Potresti provare fish su WSL = You could try fish on WSL
I use arch btw -> Su MacOS c'è fish! = On MacOS there is fish!

I hope the changes go well
