Check for new CLI version when the cli runs

[FX-Wood]

It would be great to tell users if they are using an outdated version of the CLI before they run it.

p1

• When a user runs the CLI, it checks npm for the latest version and halts execution if a newer version is found.

p2

• When execution is halted, the CLI provides a helpful error message with instructions for how to upgrade to latest

• When a user can't reach npm they should be warned that they may have an outdated version of the cli but execution should continue
