Request: Add Costs estimate

[pamelafox]

Could you add a Costs section to the README, such as https://github.com/Azure-Samples/azure-search-openai-demo/?tab=readme-ov-file#cost-estimation ?
It's recommended best practice to make sure developers understand the price consequences of deploying a project.

It'd also be great to support deployment to lower cost tiers when relevant, like we document here:
https://github.com/Azure-Samples/azure-search-openai-demo/blob/main/docs/deploy_lowcost.md

@pamelafox there is a cost estimation section in the README for each deployable platform as it depends on compute service and architectural style. You will get there once you've selected APP service, AKS or ACA deployment option from Getting Started in the README.

let me know if this is ok.

Ah, thank you! I think it would be nice to have a top-level Costs section that mentioned the differences in the architectures and suggested which one is the cheapest to deploy, for those with cost restraints. Currently, I'm not sure which one to recommend for cost-constrained developers. App Service Basic Tier isn't free, while ACA does essentially scale to 0 budget-wise, but has the ACR costs.
