Provide sample deployment code for Azure

[PacoVK]

Add Terraform example code to deploy Tapir on Azure

[TomBeckett]

@PacoVK I've got a TF example that deploys to Azure Container Apps. Would this be useful?

[cedricbraekevelt]

@TomBeckett I'm also using Azure Container Apps. Any chance you could share this?

[TomBeckett]

@cedricbraekevelt Absolutely, its fairly rough and ready but I'll raise a PR this weekend 👍

[PacoVK]

That would be awesome! Even a rough PR would help as we can iterate on that 🎉

[TomBeckett]

@cedricbraekevelt @PacoVK I've raised a PR with an example.

I've also included a basic README.md with some info if you've never deployed Tapir before. Feel free to remove this if you think this is not necessary.
