docs: Fix typos related to voyage AI

[Laxenade]

Description

Fixing a few typos on Voyage AI being used with the wrong provider. I couldn't find any usage in code where the provider is used/validated when the model "voyage-code-2" is being configured. Feel free to close this issue if you don't think it's important enough.

This addresses: #1693

@Laxenade thanks for helping out here! These are actually correct—we use "provider" to indicate the format of the API call, which in Voyage's case is the same as OpenAI, hence the "openai" provider with custom "apiBase". I don't think you're wrong though that this is confusing. What would probably be a good outcome here would be making a dedicated Voyage AI embeddings provider.

Closing this for now, but if you would have interest in contributing this, let me know!
