Go 1.23 changed the behavior of [`tls.X509KeyPair`](/pkg/crypto/tls#X509KeyPair)
and [`tls.LoadX509KeyPair`](/pkg/crypto/tls#LoadX509KeyPair) to populate the
Leaf field of the returned [`tls.Certificate`](/pkg/crypto/tls#Certificate).
This behavior is controlled by the `x509keypairleaf` setting. For Go 1.23, it
defaults to `x509keypairleaf=1`. Previous versions default to
`x509keypairleaf=0`.
