Include well-known fields such as "actual" and "url" field in JSON reporter output

[asset-web]

Initial checklist

• I read the support docs
• I read the contributing guide
• I agree to follow the code of conduct
• I searched issues and couldn’t find anything (or linked relevant results below)

Problem

Currently the reporter can output VFileMessage objects in JSON format. However, this does not include some of the well known fields, such as "actual" and "url" fields.

ref: https://github.com/vfile/vfile-message#well-known-fields

Solution

Where the additional well known fields exist can these be reported as well.

Alternatives

Create a fork of this repository to add in the additional fields in the output
