Proposal: Option for a GTE/PTE manually create a langpack even if below 95%

This is a fragmented proposal of “Delete project’s language pack when below specific percentage”.

We had feedback from the following users, and that helped to create this new proposal: @fierevere, @tobifjellner, @wolly, @nao, @ocean90, @knutsp, @yordansoares, @casiepa, and @swissspidy.

Description: The creation process would still be automatic, but there would have an option for creating it manually for specific use cases.

Goal: Some cases we have the translation for the site (which would be helpful having), but not for the WP dashboard, and we can’t provide this very helpful translation as it’s not 95% yet.
