chore(deps-dev): bump rbs from 3.10.3 to 4.0.2

[dependabot]

Bumps rbs from 3.10.3 to 4.0.2.

Release notes

Sourced from rbs's releases.

4.0.2

Release note

Library changes

rbs collection

• Fix: pathname not written to lockfile. (#2889)

Miscellaneous

• Fix test failure on Windows in ruby/ruby (#2900)
• Fix test for Ruby 4.1 (#2899)

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

• Remove deprecated types (#2880)
• Add type RBS::Unnamed::TopLevelSelfClass to core (#2362)
• Graduate bundled gems from Ruby v4.0 (#2852)
• stdlib: Add missing Psych methods and exception classes (#2850)
• Add variants with positional argument to Hash#transform_keys (#2848)
• add extra kwarg options for File#initialize and derivatives (#2798)
• pstore: fixes types, treat it as a collection (#2806)
• Add signatures for {Module,Proc}#ruby2_keywords (#2805)
• Make Zlib::GzipWriter.new level and strategy parameters optional (#2810)
• URI.(s) does string coercion (#2825)
• Fix String#append_as_bytes to accept Integer (#2817)
• [Comparable] Add in Comparable::_CompareToZero (#2697)
• [Kernel] Add Kernel.trace_var and Kernel.untrace_var (#2682)
• Add signature for Module#method_undefined (#2804)
• Fix Zlib::GzipWriter signatures (#2803)
