Tweak unbound record field error message

[zth]

Tweaking the error message for unbound record fields slightly. Interested in feedback on if you think this message is an improvement over the current, which reads roughly like:

  The record field knownKey can't be found.
 If it's defined in another module or file, bring it into scope by:
  - Prefixing it with said module name: TheModule.knownKey
  - Or specifying its type:
  let theValue: TheModule.theType = {knownKey: VALUE}

So, just changing the wording slightly.

Maybe more like "could not be found in the scope of this file" or something. The "automatically" reads to me like there is some magic going on.

How about

   knownKey refers to a record field, but no corresponding record type is in scope.
 If it is defined in another module or file, bring it into scope by:
  - Prefixing the field name with the module name: TheModule.knownKey
  - Or specifying the record type explicitly:
  let theValue: TheModule.theType = {knownKey: VALUE}

Great, updated! Merging.

@zth You only updated the first line though.

@cknitt check again.
