Replace removed top4kyear with top4kmonth

Unfortunately I had to remove the list of top packages over the last 365 days from https://github.com/hugovk/top-pypi-packages because it was using too much quota.

See https://github.com/hugovk/top-pypi-packages/pull/21, https://github.com/hugovk/top-pypi-packages/pull/20, https://github.com/hugovk/top-pypi-packages/issues/19.

Therefore we need to use top4kmonth instead of top4kyear with inputset-generator.

However on the bright side, it meant I could bump the 30-day list from the top 4,000 back to the top 5,000 packages. I've created a PR at inputset-generator to remove the top4kyear option: https://github.com/returntocorp/inputset-generator/pull/35.

That PR also renames top4kmonth to top5kmonth, so we'll need another update when that is released.
