Upgrade to Semantic Convention v1.25.0

[lalitb]

Changes

Changes in v1.25.0:

• Service attributes have been relocated to the registry
• Attributes like service.name, previously defined under resources, are now categorized under attribute_groups in the registry.
• The resource model now includes a reference to service.name as defined within the registry.

So, the code generator in generate-consts-from-spec.sh is now invoked for both resource and attribute_group.

Merge requirement checklist

• CONTRIBUTING guidelines followed
• Unit tests added/updated (if applicable)
• Appropriate CHANGELOG.md files updated for non-trivial, user-facing changes
• Changes in public API reviewed (if applicable)

FYI: open-telemetry/opentelemetry-dotnet#5539 This was removed by OTel .NET and being resurrected in contrib repo.

I think we may also move this to contrib in the future.

Yes good to discuss further on this. We can keep it in main repo as long as we can maintain/upgrade it without much of effort, which seems to be the case for now.
