Extra quotes in userAgent strings

[uvlad7]

I've implemented a ruby library that uses the user-agents.json.gz and found that sometimes there is an extra quote(s) in userAgent, like this:
"userAgent": "\"Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/89.0.4389.90 Safari/537.36",
or this:
"userAgent": "\"Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/90.0.4430.93 Safari/537.36\"",
