Conversion to v1alpha2.Function fails when editing function resources from Busola

[kwiatekus]

Description

There seem to be a problem with conversion to v1alpha2.Function when operating from busola

• by default min replicas are equal to max replicas - so the function starts with 5 pods
• if I change resources in Kyma UI I see error

Expected result

• By default, Function's min replicas should be 1.
• Clients supporting v1alpha1.Function should be abble to submit changes w/o errors during grace period

Actual result

• By default, Function's min replicas is equal to max replicas.

Steps to reproduce

Create a function in Kyma UI.
Observe that is starts with 5 replicas from the start.
Try to change the resources.

The above error was because of missing webhooks.
Already fixed by #15049.
