[BOT ISSUE] Vertex: add missing MiniMax M2 and GLM-5 MaaS entries

[github-actions]

Gap description

Vertex AI (Gemini Enterprise Agent Platform) offers MaaS entries for two publishers not currently represented in the catalog's Vertex entries: MiniMax and Z.AI (GLM). Both models are GA and available as managed APIs.

Missing model IDs

model ID	displayName	input $/1M	output $/1M	context	max output
publishers/minimaxai/models/minimax-m2-maas	MiniMax M2 (Vertex)	$0.30	$1.20	196,608	196,608
publishers/zai-org/models/glm-5-maas	GLM-5 (Vertex)	$1.00	$3.20	200,000	128,000

Note: The catalog already has MiniMaxAI/MiniMax-M3 and MiniMaxAI/MiniMax-M2.7 under the Together provider (generic IDs). MiniMax M2 on Vertex is a distinct model entry. GLM-5 is not represented in the catalog at all (the catalog has zai-glm-4.7 under Cerebras but no GLM-5).
