For some reason, permissions of `lib/net/imap/flags.rb` has 600 file permissions, rather than 664, which caused a deployment issue for us. ``` /.../ruby/3.2.0/gems/net-imap-0.3.5/lib/net/imap.rb:2389:in `require_relative': cannot load such file -- /.../ruby/3.2.0/gems/net-imap-0.3.5/lib/net/imap/flags (LoadError) from /.../ruby/3.2.0/gems/net-imap-0.3.5/lib/net/imap.rb:2389:in `<top (required)>' ```
