Add Example Attributes Of All Types

[tgoodsell-tempus]

The examples in this repo primarily use types.String and schema.StringAttribute.

I would be a big "nice to have" if this repo included examples for every supported attribute type from https://developer.hashicorp.com/terraform/plugin/framework/handling-data/attributes, as well as examples of block usage from https://developer.hashicorp.com/terraform/plugin/framework/handling-data/blocks.

This would be a big complement to the documentation as the articles mainly focus on an individual type in isolation, instead of a full working example of many of them.

It would also be nice for this to include "best practice" schema definitions, value retrieval / writing, and state writing for each type.

Perhaps even point us to the repos of some official providers with fairly complex schemas that are using the new plugin framework
