Subject: [PATCH] Fix Proc.new warnings in Ruby bindings with Ruby >= 2.7

Per Ruby 2.7's release notes[1], use the block-capturing syntax instead of
explicit Proc.new to resolve warnings like these in the Ruby SWIG APIs:

subversion/bindings/swig/ruby/svn/client.rb:640: warning: Capturing the given block using Proc.new is deprecated; use `&block` instead
subversion/bindings/swig/ruby/svn/core.rb:258: warning: Capturing the given block using Proc.new is deprecated; use `&block` instead

[1]: https://github.com/ruby/ruby/blob/v2_7_0/NEWS#proclambda-without-block-is-deprecated-

* subversion/bindings/swig/ruby/svn/client.rb:
  (set_log_msg_func, set_log_msg_func2, set_notify_func, set_cancel_func):
   Replace callback=Proc.new parameter with &callback
  (def_init_callbacks): Remove explicit nil parameters to above functions,
   leveraging deafaults

* subversion/bindings/swig/ruby/svn/core.rb:
  (add_simple_prompt_provider, add_username_prompt_provider,
   add_ssl_server_trust_prompt_provider, add_ssl_client_cert_prompt_provider,
   add_ssl_client_cert_pw_prompt_provider): Replace prompt=Proc.new parameter
    with &prompt
