✨ Improve support for CLI translations using gettext

[mjodmj]

Just adding some missing wrappings of strings around gettext which some may need for the sake of CLI i18n.

Just chiming in to say that it would be nice to have this one merged :)

Edit: this PR might also consider removing the TODO about this very change: https://github.com/tiangolo/typer/blob/046d3e2b4cb1f2feb6d94b856aa75e013d9896c6/typer/core.py#L623-L626

Thanks for your contribution!

I took the liberty of updating your PR with the latest changes from master. This looks good to me.

[ereslibre]

Thanks @svlandeg! I do wonder if we should also update some of the strings at https://github.com/tiangolo/typer/blob/74433d22b489d13fe1a0bb1f6729127cfa942996/typer/rich_utils.py#L83-L93

If you are fine with it I can create a PR if you don't want to update this one with those.

[svlandeg]

Good idea to add those @ereslibre - I've pushed directly to this PR to keep the work together. Feel free to review!

Great, thank you @mjodmj! 🤓

And thanks for the review @svlandeg 🙇

This will be available in Typer 0.9.4 in the next few hours. 🚀

@tiangolo did beat me to it! Sorry for the lag on the review and thank you everyone involved :)
