message lint rule for translations that have missing parameters

[samuelstroschein]

Problem

Variable references (expressions/parameters) that are used in source messages should be linted for translations.

In #1843 the osmosis team likely updated a source message to include parameters. Those parameters are not included in translations. No message lint rule exists that raises awareness that translations are missing (or have too many) parameters.

Updating a source message's parameters should be reflected in translations

// en
-"priceShownIn": "Prices shown"
+"priceShownIn": "Prices shown in {quote} per {base}"

Proposal

Create a message lint rule "matching expressions" that:

1. reports if a translated message includes all expressions of a source message
2. reports if a translated message includes expressions that are NOT included in a source message
