Checks for uses of the deprecated class method usages.

Example:

# bad
File.exists?(some_path)
Dir.exists?(some_path)
iterator?
attr :name, true
attr :name, false
ENV.freeze # Calling `Env.freeze` raises `TypeError` since Ruby 2.7.
ENV.clone
ENV.dup # Calling `Env.dup` raises `TypeError` since Ruby 3.1.
Socket.gethostbyname(host)
Socket.gethostbyaddr(host)

# good
File.exist?(some_path)
Dir.exist?(some_path)
block_given?
attr_accessor :name
attr_reader :name
ENV # `ENV.freeze` cannot prohibit changes to environment variables.
ENV.to_h
ENV.to_h # `ENV.dup` cannot dup `ENV`, use `ENV.to_h` to get a copy of `ENV` as a hash.
Addrinfo.getaddrinfo(nodename, service)
Addrinfo.tcp(host, port).getnameinfo
