(Parser translation) Provide multiple parsers, one for each version that we support (3.3 and 3.4) #2356
Description
Right now we only have one parser that reports itself as 3.4-compatible. But we also support passing version: "3.3.0" to prism, which means we could have multiple parsers that people could use and switch based on Ruby version. We should build this so that consumers of prism that are trying to use parser translation can start to pass the version they want to.
