[BOT ISSUE] Bedrock/Vertex: add missing claude-opus-4-8 provider variants

[github-actions]

Gap

The base claude-opus-4-8 entry was added in commit 18ca331, but the Bedrock and Vertex provider variants were not included. The existing claude-opus-4-7 model has full variant coverage (4 additional entries), while claude-opus-4-8 has none.

Missing entries

Model ID	Provider	Pricing	Parent
publishers/anthropic/models/claude-opus-4-8	vertex	Same as base ($5/$25)	—
anthropic.claude-opus-4-8	bedrock	Same as base ($5/$25)	—
global.anthropic.claude-opus-4-8	bedrock	Same as base ($5/$25)	anthropic.claude-opus-4-8
us.anthropic.claude-opus-4-8	bedrock	10% premium ($5.50/$27.50)	anthropic.claude-opus-4-8
