Nicholas Anderson 896f2b202d entc/gen: update NotSingularError godoc (#2274)
* fix: update only/onlyID comments

this patch updates the Only/OnlyID methods in the builder template from:

> // Returns a *NotSingularError when exactly one {{ $.Name }} entity is not found.
to
> // Returns a *NotSingularError when more than exactly one {{ $.Name }} ID is found.

in an effort to be more explicit in the explanation of the behavior of the methods.

* fix: update wording to be more concise from suggestion

Co-authored-by: Rotem Tamir <rotemtamir@gmail.com>

* fix: update Only wording to be more concicse

* fix: generate new files
