Improve website safety

[drepeeters]

According to https://securityheaders.com/?q=https%3A%2F%2Fdiagnijmegen.nl&followRedirects=on our website is missing some security headers. We can see if we can improve this using settings on Netlify.

A safer website could help improve the ranking of the our website and make it more findable.

I have added the following headers to website-diag/netlify.toml:

[[headers]]
for = "/*"
[headers.values]
X-Frame-Options = "SAMEORIGIN"
X-Content-Type-Options = "nosniff"
Referrer-Policy = "no-referrer"
Permissions-Policy = "geolocation=(self), microphone=()"

Missing headers are not yet updated on the securityheaders.com website. I'll check again after the weekend if these headers are updated.
