ref(core)!: Stop setting deprecated gen_ai.tool.type span attribute

MIGRATION.md

@@ -257,6 +257,7 @@ Affected SDKs: All SDKs.
 - The `gen_ai.tool.input` span attribute was renamed to `gen_ai.tool.call.arguments` across all AI integrations.
 - The `gen_ai.tool.output` span attribute was renamed to `gen_ai.tool.call.result` across all AI integrations.
 - The Vercel AI token attributes `gen_ai.usage.input_tokens.cached`, `gen_ai.usage.input_tokens.cache_write`, and `gen_ai.usage.output_tokens.reasoning` were renamed to `gen_ai.usage.cache_read.input_tokens`, `gen_ai.usage.cache_creation.input_tokens`, and `gen_ai.usage.reasoning.output_tokens`.
+- The deprecated `gen_ai.tool.type` span attribute is no longer set on tool spans.
 - Span attributes now use the shared `@sentry/conventions` package under the hood.
 
 If you reference these attributes in custom instrumentation, `beforeSendSpan`, dashboards, or alerts, update them to the new names.
