[satvik314]

Added notebook guide to use Mistral API with full OpenAI compatibility using Portkey.

Thanks @satvik314 for the PR! Could you move it to the third-party folder? And could you use mistral-small-latest or mistral-large-latest instead of mistral-medium? Thanks!

Also, could you rename the notebook to Portkey? Ideally this notebook should focus more on Portkey integrations with Mistral. Thank you!

@satvik314, could you help make the changes? Thanks!

Hey @sophiamyang, looks like this PR from Portkey got stale. I've added a new PR on the Mistral Cookbook repo. Here's the link: Portkey x Mistral Cookbook
Furthermore, I've also created a PR on Mistral docs for adding Portkey as an Observability Platform. Here's the link to it

Can you take a look at them? LGTM?

Thank you so much for contributing @siddharthsambharia-portkey ⭐

I am bit confused---would you rather have me review #130 and close this PR? Feel free to close it yourself if so 😊

I am reviewing your other PR on platform-docs-public though mistralai/platform-docs-public#174
