build(deps): bump rbs from 3.10.3 to 4.0.0

[dependabot]

Bumps rbs from 3.10.3 to 4.0.0.

Release notes

Sourced from rbs's releases.

4.0.0

Release note

RBS 4.0 ships with experimental RBS inline syntax support, allowing you to write type annotations directly in Ruby source files. See https://github.com/ruby/rbs/blob/HEAD/docs/inline.md for the syntax details.

class Calculator
  # @rbs (Integer, Integer) -> Integer
  def add(a, b) = a + b
end

Note: RBS inline is still experimental and may change in future releases.

This release also introduces two language changes: type argument support for singleton types (singleton(T)[S]) mainly for Sorbet integration, and generic type parameter lower bounds (T < S).

Signature updates

Updated classes/modules/methods: Addrinfo, Array, BasicObject, BigDecimal, Binding, CGI, Comparable, Complex, Digest::SHA2, Encoding::Converter, Enumerable, Enumerator, Enumerator::ArithmeticSequence, Enumerator::Lazy, Fiber, File, FileUtils, Float, Hash, IO, IO::TimeoutError, Integer, JSON, Kernel, Kconv, Math, Method, Minitest, Module, Numeric, ObjectSpace, Open3, OpenURI, OptionParser, PStore, Pathname, Proc, Process::Status, Psych, Ractor, Random, Random::Formatter, Range, Rational, RBS::Unnamed::TopLevelSelfClass, Ripper::Lexer::Elem, Ruby, RubyVM, SecureRandom, Set, Socket, String, StringScanner, TCPSocket, Thread, URI, URI::Generic, Zlib::GzipReader, Zlib::GzipWriter
