uuid frozen string warnings with ruby 3.4

[mscoutermarsh]

We're running:

• 2.29.1 and Ruby 3.4.1

And our logs are filled with:

uuidtools.rb:700: warning: literal string will be frozen in the future (run with --debug-frozen-string-literal for more information)

I realize this isn't technically an issue with the Datadog client. But, since uuidtools has not been updated in 5 years. It seems most likely the fix would be using something from Ruby's standard library to replace the functionality.
