Added

• Support for Ruby 3.1's shorthand hash syntax: hash => {a:, b:} => let {a, b} = hash
• functions filter: chars
• functions filter: "string" * length => "string".repeat(length) for ES2015+

Changed

• Improvements to the monorepo to ensure both the Ruby and the Node compiler versions always match
  and can get tested and released simultaneously. (Run bundle exec rake release_core.)
• Ruby 2.7 is now the minimum supported version of Ruby.
