fix(browser): enrich graphqlClient spans for relative URLs

Per #20292, graphqlClientIntegration silently skips spans for relative
GraphQL endpoints because the fetch instrumentation only sets
`url.full` / `http.url` for absolute URLs. For relative URLs it sets
the `url` attribute instead.

Fall back to `spanAttributes['url']` so relative GraphQL endpoints
get enriched the same way as absolute ones.

Closes #20292
