Incorrect steps in readme for starting eliza

[yodamaster726]

Trying the latest code, the Install went good - with 23.1. However, when following the instructions on how to start it, I ran into an issue.

This part of the online docs says that I start eliza and then start the shell but pnpm run shell is not a valid command, nor is it defined in package.json
