[Misdetection] OpenSSH private key file misdetected as <PEM certificate> about magika

[reyammer]

Thanks for opening an issue. The way I see it is that PEM is the container file format (with the classic pattern---- BEGIN HEADER NAME ---- ---- END HEADER NAME ----, and this could contain a number of different cryptographic material (a certificate, public key, private key, etc.). [1]

In which case, I would say that Magika's output as "pem" is OK, but the PEM certificate description is misleading and we should update it to be more generic. @corkamig thoughts?

Another question is whether we should try to be finer grained, and try to distinguish between PEM certificate vs. PEM "other crypto material". We are working on the next version, which introduces support for many more content types, maybe we can try to take a stab this for the next iteration...
