Update readme and contributing for StyLua advice

CONTRIBUTING.md

@@ -7,11 +7,10 @@ There are a few things which we require in any contribution:
 - This repository comes with a `.editorconfig` file, so the following requirements will be taken care of if you have [EditorConfig](https://editorconfig.org/) installed:
   - Tabs consist of 2 spaces.
   - Files end with a newline.
-  - Line endings in addon files must be Windows-Style (CRLF). This is a WoW AddOn, pretty much everyone is going to be running Windows when using or developing WeakAuras.
   - No trailing whitespace at the end of a line.
+  - We use [StyLua](https://github.com/JohnnyMorganz/StyLua) for automatic code formatting. Make sure you apply it to your changes before commiting them. There are extensions for the most common IDEs and editors as well as CLI tools to do that.
 - All user-facing strings (`names` and `desc` fields in AceConfig tables, mostly) must be localized:
   - We use a locale scraper to find translation phrases and automatically export them to CurseForge for translation. This scraper parses the addon files, looking for tokens that look like: `L["some translation phrase"]`. You must use double quoted strings, and name the localization table (found at `WeakAuras.L`) `L` in your code for this to work properly.
-- When writing a new file, avoid using semicolons. When modifying code in an existing file, try to be consistent, but err on the side of no semicolons.
 - New features should be indicated by concatenating `WeakAuras.newFeatureString` onto the associated translation phrase. We will remove the new feature indicator approximately 3 months after the first release.
