Pants

The `./pants validate` step in a Gtihub action failed for me on
```Would update testprojects/src/python/docker/BUILD:
  - Format with Black```
which is fine, but it was well hidden….

That's `pants update-build-files`. The error message will be improved in a few minutes with my next PR :slightly_smiling_face:

I know, just that it didn’t stand out. Looking forward to the improvement :slightly_smiling_face:

Running this interactively, it seems fine.. just in the gh action there’s alot of other stuff going on, burying it a bit too deep… :wink:

<https://github.com/pantsbuild/pants/pull/13432>

```Would update dir/BUILD:
  - Add a new line
  - Reverse lines

To fix `update-build-files` failures, run `./pants update-build-files`.```
