✨ 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:

typer/typer/core.py

Lines 623 to 626 in 046d3e2

	# TODO: explore adding Click's gettext support, e.g.:
	# from gettext import gettext as _
	# with formatter.section(_("Options")):
	# ...

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

typer/typer/rich_utils.py

Lines 83 to 93 in 74433d2

	DEPRECATED_STRING = "(deprecated) "
	DEFAULT_STRING = "[default: {}]"
	ENVVAR_STRING = "[env var: {}]"
	REQUIRED_SHORT_STRING = "*"
	REQUIRED_LONG_STRING = "[required]"
	RANGE_STRING = " [{}]"
	ARGUMENTS_PANEL_TITLE = "Arguments"
	OPTIONS_PANEL_TITLE = "Options"
	COMMANDS_PANEL_TITLE = "Commands"
	ERRORS_PANEL_TITLE = "Error"
	ABORTED_TEXT = "Aborted."

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

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