cvlib/context: Update docs for ctx.alog() no-op

Calling ctx.alog() in a studio template rendering context is a no-op.
This is by design - there are no typical use cases for writing an audit
log for potentially 1000s of devices during a CLI generation run.

Studio developers are instead invited to use the ctx.info/warn etc.
logging calls instead.
