[evidence] spark --version returns error instead of version number

[Acone8]

Before: spark --version returns "spark: error: the following arguments are required: command" instead of the version number. spark version also returns an invalid choice error.

After fix: spark --version correctly returns "spark-cli 0.1.0".

Repro steps:

1. Run spark --version in terminal
2. Observe: spark: error: the following arguments are required: command
3. Run spark version
4. Observe: error: argument command: invalid choice: 'version'
