templates: adjust entry.server for single fetch

[Aleuck]

I noticed that the templates for create-remix have been updated to have v3_singleFetch enabled by default but didn't update the entry.server code to match what is recommended on the docs.

This caused a bit of confusion for me as I didn't understand there was a new export key for the stream timeout.
