Validator generation automatically enforces 'NotEmpty()' for non-nullable strings

[David1Socha]

I'm dealing with a codebase where some entities have strings that are non-nullable, but expect String.Empty to be set under certain conditions. Currently, when using the EntityFrameworkCore.Generator tool with validator generation enabled, NotEmpty() validators are added to all non-null string fields. However, this seems slightly overbroad, since empty string is a valid input for the database, and may be a desired input.

Would it be possible to either change the default validator generated for non-nullable strings from NotEmpty to NotNull, or to add a boolean option to the validators configuration section that changes the default validator generated for non-nullable strings from NotEmpty to NotNull?

If either such change would be acceptable, I'd be happy to submit such a PR. Thanks for creating this helpful library!

yes, that seems fair. NotNull is more correct. If you are up for a PR, I'd gladly except.
