JSON needs escapes for passing params in prefect run cloud

[zhen0]

Description

If I try to run a flow using the CLI and add params using the example in the help section (from calling prefect run cloud -h) I get an error message. For example:
prefect run cloud -n Params-New -p Jenny -ps {"c":3}
Gives the following error:
json.decoder.JSONDecodeError: Expecting property name enclosed in double quotes: line 1 column 2 (char 1)

If I enter the params as a string with an escape round other speechmarks, it works:
For example:
prefect run cloud -n Params-New -p Jenny -ps "{\"c\":3}"
works fine

Expected Behavior

Best case scenario:
prefect run cloud -n Params-New -p Jenny -ps {"c":3} works fine.
Second best:
We update the docs to show an example with correct JSON formatting.

Reproduction

prefect run cloud -n FLOWNAME -p PROJECT -ps {"c":3}

Environment

@zhen0 - if you put your parameters within single ticks it will work as you expect:

prefect run cloud -n FLOWNAME -p PROJECT -ps '{"c":3}'

you can even include spaces!

prefect run cloud -n FLOWNAME -p PROJECT -ps '{"c" : 3}'

I'll update the example documentation to clarify this point.
