We're adding Ruby support to CodeQL (the scanning engine used in code scanning by default). It's our top requested language, and one we use extensively internally. Adding each new language to CodeQL takes about 6-9 months and needs a team to maintain it in perpetuity, which is why we don't have it yet, but we're starting that work now.
The other languages we hear the most demand for CodeQL support on are PHP, Kotlin and Swift. We'll get to all of those - it will just take a little time.
In the meantime, all of the code scanning experiences are extensible, so you can use other scanning engines with it, like Brakeman for Ruby.
