Bug: Prism::Translation::Parser breaks on numbered block params

[exterm]

Minimal example:

Prism::Translation::Parser.parse("find { _1 }")

fails with "undefined method `parameters' for @ NumberedParametersNode":

/home/philip/.asdf/installs/ruby/3.1.2/lib/ruby/gems/3.1.0/gems/prism-0.20.0/lib/prism/translation/parser/compiler.rb:1752:in `visit_block': undefined method `parameters' for @ NumberedParametersNode (location: (1,5)-(1,11)) (NoMethodError)
