chore: fix, add and sort icons

Fix:

ruby's official logo is falling down: https://www.ruby-lang.org/en/about/logo/
*.com is DOS binary format: https://en.wikipedia.org/wiki/COM_file
use editorconfig logo for .editorconfig
bare metal programs also use *.lib and *.a as their static library extension
use linux icon is not appropriate
however, bare metal programs don't support dynamic library
so use windows icon for *.dll
use vim icon for _vimrc and _gvimrc, which are vimrc filename on windows
use fennel icon for .fennelrc and fennelrc

Add some missing icons from:

- https://github.com/lambdalisue/vim-nerdfont/blob/master/assets/json/basename.json

Sort them alphabetically
