pygettext: Add support for multi-argument gettext functions

[tomasr8]

Feature or enhancement

Proposal:

This came up while adding translation tests for various stdlib modules: #124295 and #126698. More specifically: #124295 (comment)

pygettext currently only supports single-argument gettext and its aliases (can be controlled via CLI arguments). pgettext, ngettext, etc., are not supported. pygettext should support these by default. I'm gonna take a stab at this hopefully this week :)

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere

Thank you @tomasr8. I did not expect that you can do this before making pygettext to use AST parser.
