Update semconv JSON schema for entities

[smith]

• Add entity_associations for metrics
• Update display_name description to be more generic
• Replace resource with updated entity schema

To try this out in VS Code, update the .vscode/settings.json in your semconv checkout to point to "../weaver/schemas/semconv.schema.json", assuming your weaver and semconv checkouts are in sibling directories. You may need to close and reopen the semconv window.

When this is merged and a release happens a PR to semconv can be made to update the version of the JSON schema.

Thanks for updating this! A few comments on what we can/should support right now.

[smith]

@jsuereth I'll keep the parts that don't exist yet in this PR and move it to draft. I'll open a new PR with the remaining changes that can be made now. Thanks for looking!

[jsuereth]

Please see: #735

I'm actually changing how we plan to do descriptive and identifying attributes for various internal reasons around attribute sharing in Weaver.

[smith]

@jsuereth I added role as an enum in 590113d. Let me know if things look right here now, as I also took out the things that don't exist yet.

[jsuereth]

This looks good now, but you probably need to merge in main, where role was already added.
