Bad JSON format for 'lshw'

[Digimer]

I tried to submit this as a ticket to
https://ezix.org/project/newticket#ticket but it wouldn't accept the
captcha test. Posting here in case I can get to the 'lshw' dev (or
package maintainer) through Fedora. This is tested on Fedora 33 (and
CentOS Stream 8, fwiw).

I'm working on a program to process lshw data, and the XML data is fine,
but the JSON output format is invalid.

Example in XML;

# lshw -class disk -class storage -xml
