chore: Fix Ruby Version Management

Prior to this change, the RUBY_REQUIREMENT file was used to keep Ruby versions in sync,
however toys will not detect a change to gem since the gemspec file was unaltered.

Rather than modify toys to be more flexible in this case, it will be easier to update the Ruby requirement
in each gemspec using a script.

The script will write out diagnostic output of the gemspecs that were changed. E.g.

```ruby

$> bin/update-ruby-version 3.2

Updating Ruby version requirement to: >= 3.2
Finding gemspec files...
Found 62 gemspec files to update:
Updated: helpers/mysql/opentelemetry-helpers-mysql.gemspec
Updated: helpers/sql/opentelemetry-helpers-sql.gemspec
Updated: helpers/sql-obfuscation/opentelemetry-helpers-sql-obfuscation.gemspec
Updated: helpers/sql-processor/opentelemetry-helpers-sql-processor.gemspec
Updated: instrumentation/action_mailer/opentelemetry-instrumentation-action_mailer.gemspec
...
Updated: resources/google_cloud_platform/opentelemetry-resource-detector-google_cloud_platform.gemspec
Updated: sampler/xray/opentelemetry-sampler-xray.gemspec

Summary:
- Total files found: 62
- Successfully updated: 62

Done! All gemspecs have been updated to require Ruby >= 3.2
