Update rb-sys to 0.9.102 for ruby 3.4 compatibility

[casperisfine]

Otherwise it fails with:

LoadError: /tmp/bundle/ruby/3.4.0+0/gems/tiktoken_ruby-0.0.8/lib/tiktoken_ruby/tiktoken_ruby.so:
undefined symbol: ruby_abi_version - ruby_abi_version (LoadError)

However compilation is now failing with:

Which I don't know how to fix. @ianks could you lend me a hand here?

[casperisfine]

Nevermind, the compilation failure was because I forgot to rebase my fork 🤦

[casperisfine]

Hum, seems like there's no version of rb-sys compatible with both 3.4 and 2.7?

rb-sys is (painfully) compatible down to 2.6

I think this error is a bundler issue?

  	There are no versions of bundler (= 2.5.18) compatible with your Ruby & RubyGems
  	bundler requires Ruby version >= 3.0.0. The current ruby version is 2.7.8.225.

Anyway, @IAPark we should probably drop 2.7 support since it's EOL and rb-sys will

@IAPark just saw you are looking for maintainership help. Happy to lend a hand here if you send inv ❤️
