Default rules showing incorrect validation

[alsoto25]

Prerequisites

• I have searched for duplicate or closed issues

Describe the issue

The rules EmptyOrLetters, NoEmptySpacesOnly, MinCharacterAmount and CharacterAmount have validation functions that show incorrect results or have unexpected results.

• EmptyOrLetters: An input like John123 passes the validation even with numbers in it.
• NoEmptySpacesOnly: The Validator passes the input through the String.trim() function which means this rule always returns true
• MinCharacterAmount: If a field doesn't have the required rule, passing an empty value on a field with a rule like minCharacterAmount(3) show the field as valid
• CharacterAmount: Same case as MinCharacterAmount

Steps to Reproduce

1. Initialize form validation with any of the rules
2. Fill input with respective cases noted in description
3. See error

Expected Behavior

• EmptyOrLetters: Either change the name of the rule to something less misleading like atLeastOneLetter or change the validation of this rule.
• NoEmptySpacesOnly: The rule should be removed or the validator options should allow a flag to know if .trim() should be used by default on values or not.
• MinCharacterAmount: I think this is working as expected, but we should be clear with how this behavior
• CharacterAmount: Same case as MinCharacterAmount
