Support exteralized attachments in the html report

[mpkorstanje]

🤔 What's the problem you're trying to solve?

The html report currently inlines all attachments as base 64 encoded json strings. While this allows for a single file report, it can explode in size quickly.

✨ What's your proposed solution?

With cucumber/react-components#353 we now have the ability to exteralize these attachments but we don't make use of this yet.

This mechanism could potentially also be used to link to other external resources.

⛏ Have you considered any alternatives or workarounds?

No response

📚 Any additional context?

One of the problems to solve is that plugins currently only accept a single configuration parameter.
