Add new Python 3.14 argparse.ArgumentParser constructor parameters

[edgarrmondragon]

These are

• suggest_on_error, added by GH-99749: Add optional feature to suggest correct names (ArgumentParser) cpython#124456, made keyword-only by gh-133300: argparse: make suggest_on_error a keyword-only parameter cpython#133302
• color, added by gh-130645: Add colour to argparse help cpython#132323
• gh-133653: Fix argparse.ArgumentParser with the formatter_class argument cpython#133813

Our policy is generally to not add features for new Python versions until the first beta, but that's tomorrow so I think it's fine to get this in.

Suggested change

	suggest_on_error: bool=...,
	color: bool=...,
	suggest_on_error: bool=False,
	color: bool=False,

I think we didn't fill in defaults here because at runtime they go through **kwargs. Let's add defaults for the new parameters at least, and if you like we can add defaults for the rest at some point too.

Would you prefer if I add the missing defaults in this PR or in a separate one?

[JelleZijlstra]

Let's do it in another PR, I'll merge this one
