[patch] add forgotten documentation bits for issuer altname

[Brad Hards]

Hi,

While poking around the documentation, I realised that I had forgotten part of 
the documentation - the "since" part that generates the "new in 2.10.0" index.

Patch attached. I tested this by re-generating the documentation and making 
sure it appears in the html output.
