[BOT ISSUE] Bedrock: add missing available_providers to Llama 4 Scout and Maverick base entries

[github-actions]

Bedrock Llama 4 base models missing available_providers

The base Bedrock model entries for Llama 4 Scout and Maverick are missing available_providers: ["bedrock"], even though their geo-prefixed variants (us.meta.llama4-*) correctly have it and reference these as parents.

Affected models

Model ID	Current available_providers	Should be
meta.llama4-scout-17b-instruct-v1:0	(field absent)	["bedrock"]
meta.llama4-maverick-17b-instruct-v1:0	(field absent)	["bedrock"]

Both entries use format: "converse" (Bedrock's native format) and are referenced as parent by their us. variants which do have available_providers: ["bedrock"]. The base entries also lack pricing — Bedrock publishes per-token pricing for Llama 4 models but the values are not included here as they could not be confirmed from two independent sources.

Evidence

• us.meta.llama4-scout-17b-instruct-v1:0 (line 9627) → parent: "meta.llama4-scout-17b-instruct-v1:0", available_providers: ["bedrock"]
• us.meta.llama4-maverick-17b-instruct-v1:0 (line 9615) → parent: "meta.llama4-maverick-17b-instruct-v1:0", available_providers: ["bedrock"]
• Comparable model meta.llama3-3-70b-instruct-v1:0 correctly has available_providers: ["bedrock"]
