fix:Cosmos SDK Intro topics - make all references to Cosmos SDK consistent, apply guidelines

[barriebyron]

Summary of Bug

The Cosmos SDK docs refer to the Cosmos SDK in a variety of ways, make them all consistent as Cosmos SDK. Our docs traffic increases as more cosmonauts search for information about the Cosmos SDK. Rarely do users look for "the SDK" when they search on the web. As more users start to use the Cosmos SDK and the docs, we want each page to stand on its own as a trusted resource to share, teach, and inform.

Version

Since @brennhill has already resolved this issue, I guess it won't makes sense for me to do the same changes again and take credit from him.
