Add extra info when a value with a wildcard might not be in quotes

[imjoehaines]

Goal

This PR adds an info message when an argument that allows a wildcard is used and we encounter an unknown value error. For example, the following command will cause an unknown value error because --base-url has two arguments:

$ ./bin/cli upload-browser --base-url 123 xyz

If a user is using a wildcard argument and we get an unknown value, it's likely that this is because the wildcard isn't wrapped in quotes — i.e. --base-url * should be --base-url "*"

This is hard to know for sure because asterisk expansion happens in the shell before the CLI is run, so we have to guess that this happened

Suggestion added to make it clear "why", though it may just confuse matters. Take it or leave it!

Yeah this makes a lot of sense — it's google-able if someone isn't familiar with "shell expansion"
