Support Inlang Message Format

[johanohly]

Describe the problem

Using the Inlang Message Format with variants and gendering, results in Weblate misunderstanding what strings are meant for translating (as they veer off the json key-value structure of basic translations).

Describe the solution you would like

Screenshots

The following translation does not work well with Weblate:

    "going_count": [
      {
        "declarations": [
          "input count",
          "local countPlural = count: plural"
        ],
        "selectors": [
          "countPlural"
        ],
        "match": {
          "self_going=*, count=0": "No one going",
          "self_going=true, countPlural=*": "{count} going",
          "self_going=false, countPlural=one": "{count} other going",
          "self_going=false, countPlural=other": "{count} others going"
        }
      }
    ]

For reference, it results in the following (to be expected):
