DeepL pt@formal (Portuguese (formal)) does not support automatic suggestions

[matzeeable]

Describe the issue

We have configured pt@formal (Portuguese (formal)) for a component. When we open "Automatic suggestions" for a translation, we do not get any response from DeepL translator.

Perhaps this is related to #9274

I already tried

• I've read and searched the documentation.
• I've searched for similar filed issues in this repository.

Steps to reproduce the behavior

1. Create pt@formal (Portuguese (formal)) for a component
2. Try to get automatic translations from DeepL for a string

Expected behavior

The DeepL documentation at https://developers.deepl.com/docs/v/de/api-reference/languages offers PT-PT translations with formality support:

  {
    "language": "PT-PT",
    "name": "Portuguese (European)",
    "supports_formality": true
  },

In the following lines, Weblate already maps pt to pt-pt, so I think this should work as expected:

weblate/weblate/machinery/deepl.py

Lines 34 to 38 in 69c4f6d

	language_map = {
	"zh_Hans": "zh",
	"zh_Hant": "", # Traditional Chinese not supported but would map to zh
	"pt": "pt-pt",
	}

In docker, it appears that the call to DeepL API returns code 200:

I doubt that language code aliases work across variants, so we need to add those as well.
