Fix rails 7 deprecation warning

[adfoster-r7]

Fixes an issue when running Rails 7 and RubySMB - https://github.com/rapid7/metasploit-framework/pull/17291

When running Metasplotit's secrets dump module we get a deprecation warning from rails:

DEPRECATION WARNING: Rails 7.0 has deprecated Enumerable.sum in favor of Ruby's native implementation available since 2.4. Sum of non-numeric elements requires an initial argument. (call    ed from block in decrypt_supplemental_info at /tmp/metasploit-framework/modules/auxiliary/gather/windows_secrets_dump.rb:658)

Tracked the warning down to:

https://github.com/rails/rails/commit/afa83350deef906ed01b7acb5da6e9285aab661f#diff-55ebe1b9975bc2c8530cd262bd89b31434a4a852f39d1e79a17dcf7f9f03b8ffR66-R68

Because BinData's integers don't pass the first.is_a?(Numeric) logic check Minimal example in Rails prompt:

>> [BinData::Int64le.new(123)].sum
DEPRECATION WARNING: Rails 7.0 has deprecated Enumerable.sum in favor of Ruby's native implementation available since 2.4. Sum of non-numeric elements requires an initial argument. (called from <top (required)> at (irb):6)

Whilst the following works in both Rails and Ruby

>> [BinData::Int64le.new(123)].sum(&:to_i)
=> 123

Confirmed this works as expected:

 ~/git/metasploit-framework │ land-pr17291:pr/17291 ?17  rails console                                                               ✔ │ 4s │ 3.0.5 Ruby │ 06:07:45 PM

One thing to note with this new behavior is that nested array behavior appears to behave a little differently:

irb(main):008:0> [[3],[33]].sum
=> [3, 33]
irb(main):009:0> [[3],[33]].sum(&:to_i)
/home/gwillcox/.rbenv/versions/3.0.5/lib/ruby/gems/3.0.0/gems/activesupport-6.1.7/lib/active_support/core_ext/enumerable.rb:41:in `map': undefined method `to_i' for [3]:Array (NoMethodError)                                                                                    
Did you mean?  to_s                                                                                     
               to_a                                                                                     
               to_h                                                                                     
irb(main):010:0> 

Don't think it should be an issue here since we aren't using nested arrays but did want to call it out as a gotcha in terms of changed behavior to be aware of.
