Fix ResourceInstanceDataType to use the language passed for calculating the display value

This fixes the issue where the display value being calculated for a ResourceInstanceDataType object wasn't using the language value passed to the function and always defaulted to the currently active language.

Further comments

I have targeted this change to the dev/7.6.x branch because I found it on our 7.6 install but I also believe this to be a bug in the 8.x version as well. If it makes more sense to target v8 I can change the PR.

Could you add a changelog entry to the 7.6.20 release notes?

@chiatt, added.

I was waiting to see if targeting 7.6.x was fine 👍
