docs(platform-server): fix renderModule usage guidance with Ivy (#37296)

Before the introduction of the Ivy renderer, users would compile
their applications and use the resulting factories for SSR, since
these post-compilation artifacts ensured faster delivery. Thus,
using the original module as the rendering entrypoint was
considered suboptimal and was discouraged.

However, with the introduction of Ivy, this guidance is no longer
applicable since these factories are no longer generated.
Comparable speed is achieved using the factory-less module
renderer, and so we update the guiance in the docs for the method.
