More Octicon fixes

[jolheiser]

Just a few more SVG fixes I've noticed as I interact with gitea.com

Changing the padding-right to margin-right fixes the compare icon.

This one has actually been present since before the SVGs, it's just that the wrong font never took up room so it went unnoticed. 😉
Can you spot the difference?

A popular repository will gain many repos stars

I considered adding the "correct" octicon for the org repo create, but I decided to remove it instead as none of the other buttons on that page have an icon.
