Make sample config json valid

[sycdan]

Last night I happened to search for "cli budgeting tool", fully expecting Google to laugh in my face because why would such a thing exist, at which point I would have proceeded to write this exact tool only in Python. However! This was the first hit and I loved it instantly.

I have just started getting it set up, but my first order of business was to make a parser for my Amex statements, and I thought I'd share.

Bonus documentation changes:

• configuration:
  • Add closing square bracket to autoCategorization array in sample config
  • Remove a couple of trailing commas for consistency
  • Use tabs throughout for consistency
  • Remove trailing whitespace
  • Remove extra tab level in amount description
• usage:
  • remove unused --input argument name

@sycdan - I'm so sorry for the delay here! Thank you so much for your contribution! I'm right in the middle of getting another project out but I'll come back and review in the next couple of days. Thank you for making my day with a PR!

If you could check the minor comments here and run the listing/formatting locally, I'm fine with merging:
