[ruby/prism] Add support for `Prism.parse(foo, version: "current")`

2025-10-16T12:34:14+00:00

The docs currently say to use `Prism.parse(foo, version: RUBY_VERSION)` for this.
By specifying "current" instead, we can have prism raise a more specifc error.

Note: Does not use `ruby_version` from `ruby/version.h` because writing a test for that is not really possible.
`RUBY_VERSION` is nicely stubbable for both the c-ext and FFI backend.
