Updates CLI deployment run --help text so it renders for more args

[discdiver]

Closes #11957

A number of arguments were not showing in the CLI for prefect deployment run --help. Some of the code had incorrect formatting (multil-line strings appear to need to be wrapped in parentheses for typer to render them) and some items were missing text.
Looked at all help=" for CLI commands.

This omission was noted by a participant at PACC this week - nice to be able to show the fix is in flight. :)
