Change ordered list order, lower-alpha before lower-roman

[zmanion]

What are you trying to accomplish?

Change ordered list styles used in markdown in at least issues and wikis to use what seems like the more common and intuitive order: decimal, lower-alpha, lower-roman. This alternates numbers and letters and seems to follow more common convention, at least among U.lS. english styles. I looked at least briefly and couldn't find style guidance or use of the current order over the proposed new order.

I read and tried various ways to override the order just for my content, but this seems to be difficult if not impossible since GitHub blocks various style/CSS modifications (probably for legitimate security reasons).

Here are a semi-related issue and discussion.

What approach did you choose and why?

Changed the order, simplest possible change. Note that I did not test this at all.

What should reviewers focus on?

Whether or not to change the order. Some may prefer the current order? Existing ordered lists would change.

Can these changes ship as is?

I think so.
