pbts does not generate comments for enum properties

[thomasttvo]

Hi! 👋

Firstly, thanks for your work on this project! 🙂

Today I used patch-package to patch protobufjs@6.11.2 for the project I'm working on.

I found that pbts copies the comments for class properties just fine but ignore all comments for enum properties

Here is the diff that solved my problem:
