We can get translations with invalid plural keys from Crowdin or from custom overrides. Currently, this will raise an error and the locales won’t be outputted at all. This patch addresses this issue by using the new `strict: false` option of our `messageformat-wrapper` gem, allowing to generate locales even if there are invalid plural keys present.
