add translations to debug view

[missinglink]

There is currently no entry in the ?debug info showing if/when a document has been translated via the language service (ie. placeholder).

This can make debugging quite frustrating, which is why i've added it here.

Interestingly, the response is quite verbose, possibly why it was never logged in the first place, but also indicates that we can probably optimise this operation.
