Workshop Script Update

[frank-aleo]

Why

Added more expressive scripts that exposes echo commands being run and brief explanations for inputs and outputs. It doesn't take the place of the README.md (and eventual tutorial in the documentation), but offers much more of a standalone narrative in the terminal. The user can run the entire script, and then read their terminal to see commands and outputs without hopping around too much.

Changes

• Added more expressive, narrative scripts, with the exception of battleship, since it's much more complex and the README.md does a better job.
• Also added fixes on self.caller -> self.signer in the battleship example to ensure records are owned by the signer not the program owner.
• Scripts have all been modified to use inputs inline, so when we remove input files, the scripts are independent from them and will not break.
• All README.mds have been updated to the most current tutorial documentation (Frank workshop upgrades welcome#295)

Testing

All scripts have been tested locally. They compile and run end to end without errors.

@frank-aleo Can you remove the input files for the workshop examples in this PR as well?
This will prevent downstream breakages over the next Leo release

Appreciate the comments and review @collinc97.

1. Added steps back to the README.md so it matches run scripts.
2. Simplified "how to run", added correct links, added explainers.
3. Removed all input files from examples.
