Fixes flake8 errors:
support/scripts/pkg-stats:1013:133: E501 line too long (164 > 132 characters)
support/scripts/pkg-stats:1018:36: F541 f-string is missing placeholders
support/scripts/pkg-stats:1110:199: E261 at least two spaces before inline comment
For the first and the last one, we chose to split the long lines rather
than adding noqa: 501. Indeed, the long lines make it very unreadable,
and there are relatively natural places where the line can be broken.
Also split a line just below the second one in a similar way.
The f-string on 1018 doesn't need to be an f-string.
