Merge #657

657: Fixes list dist uploads. r=AstraLuma a=pathunstrom

Prevents `examples.zip` from being included in `dists` 

Tested the comprehension on a xonsh container:

```
<user>`@8f257c1bbfc7` ~/tmp # touch dist1
<user>`@8f257c1bbfc7` ~/tmp # touch dist2
<user>`@8f257c1bbfc7` ~/tmp # touch dist3
<user>`@8f257c1bbfc7` ~/tmp # touch examples.zip
<user>`@8f257c1bbfc7` ~/tmp # dists = [f for f in pg`**` if '+' not in f.name and 'examples.zip' not in f.name and f.is_fi
le()]
<user>`@8f257c1bbfc7` ~/tmp # dists
[PosixPath('dist1'), PosixPath('dist2'), PosixPath('dist3')]
```
