[Feature] Add more entries to response.securityDetails (and HAR output)

[Rafiot]

The method response.securityDetails returns a few details regarding the certificate, but I'd love to get a few more, especially hashes of the certificate and/or the complete certificate itself (maybe as an option?).

I want to use it in PlaywrightCapture (via the HAR output) and ultimately in lookyloo in order to display more information about the page we're investigating. I think having that feature available in response.securityDetails would be useful for many other people than me.

Down the line, I'd like to push the certificates captured on lookyloo to CIRCL passive SSL service, which will require the full certificate.

Relates #6759

Could you be more specific as to what you would like to see? This largely falls outside of the Playwright scope, so unless it is needed for testing, we are likely to close it.

It definitely relates to #6759. I'd like to be able to get the serial number and the hashes (sha1 and sha256, at least) in response.securityDetails (and in the HAR export). The full certificate is definitely optional (but nice to have if possible).

I'm not using Playwright for testing, but that sounds like a useful information for testing to me?

Folding into #6759!
