[BUG] Cannot read properties of undefined (reading 'start')

[Rolv-Apneseth]

Describe the bug
First, thank you for making this.

As for the issue, while running linkspector check on a json file, I am getting the following error:

💥 Error: Cannot read properties of undefined (reading 'start')

To Reproduce
Running linkspector check with the following minimal json file causes it for me:

{
    "images": [
        "https://cdn.britannica.com/75/178475-050-E9212E3D/Pyramid-of-Khufu-Giza-Egypt.jpg"
    ]
}

The issue does not happen when I remove the array and just have "images": "..." directly.

Expected behavior
I would expect this to work, but a better error message to give a better idea of what the actual issue is, or at least a line number pointing to the offending link, would be nice too.

I'm also experiencing this in a totally normal Markdown file and I have absolutely no idea why. This is the most I get:

I'm really loving linkinspector otherwise. Thanks so much for your hard work on this!

I was facing the same error message on some of my repositories and after some debugging I found the root cause: a wrong link structure.

In some of the files I have the following content:

Instances of abusive, harassing, or otherwise unacceptable behavior may be reported to the community leaders
responsible for enforcement at [info@example.org]. All complaints will be reviewed and investigated promptly
and fairly.

The link to the email address was not fully completed, missed the ( and ). Changing the structure to the right pattern [info@example.org](info@example.org) the execution of the linkspector is successfull.

It seems that there is a side corner scenario for wrong link patterns not evaluated by linkspector. It could be great to check it instead of this current annoying error.
