Validation Object expects all properties to be set

[IamSebastianDev]

Describe the bug

When setting validation on a Collection, all properties need to be set, instead of just available. While this is not necessarily a problem, as the property can receive a empty [] containing no validators, a better qol improvement would be to change the typings of the validation object to a Partial<T>.

To Reproduce
Steps to reproduce the behavior:

1. Create a Collection and add a Schema
2. Add a Validation Object to the Collection
3. You now see that all properties must be set

Expected behavior
I expect to only set the fields that I would want to validate

Screenshots

Additional context
This is a TypeScript only issue, as the bug in question stems from the implemented type system for the validation.
