feat: have --print-config output valid JSON data

[weilbith]

Expected Behavior

If I run commitlint --print-config --color=false I would like to be able to read a valid JSON that I can parse for example with jq. I would like to go this path, because this way it fully resolves extends settings etc. So I get the complete configuration.

Current Behavior

The output is not valid JSON as keys are not wrapped with quotation marks and single quotation marks are used for values. I tried to use sed substitution to solve the issue, but this is very complex and there any many edge-cases like quotation mark escaping in string values etc.

Affected packages

• cli
• core
• prompt
• config-angular

Possible Solution

Print out valid JSON like JSON.stringify content to stdout.

Context

I need to access commitlint configuration parameter including presets in a bash script without node.
