[Power BI] Detailed document for connecting to data

[surendhar1992]

1. I wish the readme document on how/what type of cost analysis exports are required
2. How to connect to a storage account, The SAS token update is not helping as we need to create new data source update settings, etc.

@surendhar1992 Can you clarify what you're looking for with respect to the exports? We say to create cost exports and then call out the rest are optional, but the reservation recommendations are required for that page in the Rate optimization report. Are you saying that's not clear or that you'd like additional information? Happy to update the docs, but I want to make sure we know what we're updating.

Actually, are you setting this up for Power BI on top of raw exports in storage or are you using FinOps hubs? I think the documentation for Power BI reports is not clear enough about the types of exports used. Would you mind sharing the doc URL you were looking at to confirm?

Can you also clarify what you mean about the SAS token comment? I'm not quite following.

@Zeo-shark Would you mind taking a look at this and seeing if you spot any opportunities to clean up the docs?
