Fix links on web site

[ppkarwasz]

On our website we should fix:

• broken links (4xxs),
• links to non-canonical URLs (3xxs).

Also some kind of canonicalization would be advised. Since we run on Apache with mod_dir and mod_negotiation my personal preference would be to:

• remove trailing index and index.html from internal links (exception: the relative 'index.html' should be converted in ./)
• remove trailing .html from internal links. We might even internationalize some pages or provide machine-readable alternatives to HTML (e.g. SBOM if the client asks for application/vnd.cyclonedx+xml).

We might use some tool like Screaming Frog to detect the broken links.

@ppkarwasz, could you explain how we can use <place-your-3rd-party-link-checker-SaaS-here>? Do you suggest a maintainer creating a personal account and occasionally checking the report?

Screaming Frog offered us a free of charge full license of their link checker (cc @grobmeier ). I will be running it regularly to fix the broken links on our website.

The first results using this tool:
