feat(names): Include GraphQL operation names in span names

[andreiborza]

Includes graphql.operation.name in GraphQL span names when available, so a named query becomes GraphQL query findBookById instead of GraphQL query. The existing fallbacks still cover anonymous operations and processing spans.

Operation names are normally stable, meaningful identifiers, and keeping them lets users distinguish queries and mutations in span grouping. This accepts the possibility of client-generated high-cardinality names discussed in #615, and aligns with OTel naming apart from our GraphQL prefix.

Otel does warn that these could be high-cardinality, but in practice we've never seen that. I also tried looking through public github repos to see if users define dynamic operations and didn't find any. Happy to close/revise if anyone has more experience with GraphQL and thinks this is a terrible idea.

[Lms24]

I'm generally fine with this and happy to approve but I feel like this needs a product-sign-off.

Just one technical suggestion: Let's add a sentence about diverging from the OTel naming schema in otel_notes.
