Fix future date issue

[sethherr]

The month was off by 1 when translating the date!

Running this in console and getting the shown responses back was wild!

Time.current
=> "Wed, 24 Jun 2020 11:20:48 CDT -05:00"
I18n.l(Time.current)
=> "Wed, 24 Jul 2020 11:02:51 -0500" # wtf?
I18n.l(Time.current.beginning_of_year)
=> "Wed, 01 Feb 2020 00:00:00 -0600" # WHOAH, WHAT!!?
I18n.l(Time.current, format: :dotted)
=> "2020.6.24" # and this is CORRECT!

I found an answer in this stack overflow question.

In PR #1630 I removed the nil columns because they were causing problems with the translation normalizing. Reverting that - putting a nil row back in month_names and abbr_month_names fixed the issue.

So... still running into the issue that led to deleting those nil values - where my local bundle exec bin/rake prepare_translations doesn't normalize in the same way that CircleCI does.

I tried to figure out a quick fix but couldn't. I opened an issue in the i18n-tasks gem.

For now, I just manually edited the file locally to match the CircleCI whitespace, after running bin/rake prepare_translations
