Set default max scale to 5 replicas and a 10% increment

Browse Source 
Sets a new default maximum scale limit of 5 replicas out of
the box for CE users, CE meaning "Community" rather than
"Commercial".

The increment factor of 10 vs 25 should not make a difference
to genuine community and hobbyist users.

Tested and verified with unit tests and hey with a CE cluster
where the maximum limit was reached over several minutes,
finally going back to 1 replica.
