 * This function returns an array of validators, in the validator key => options array form.
12 
 * Possible options:
13 
 * - name (required): name of the validator
14 
 * - component types (required): defines which component types can be validated by this validator. Specify 'all' to allow all types
15 
 * - negatable (optional): define whether the rule can be negated, meaning it will validate the inverse of the rule.
16 
 * - custom_error (optional): define whether a user can specify a custom error message upon creating the validation rule.
17 
 * - custom_data (optional): define whether custom data can be added to the validation rule
18 
 * - min_components (optional): define the minimum number of components to be selected for creating a validation rule
19 
 * - max_components (optional): define the maximum number of components to be selected for creating a validation rule
20 
 * - description (optional): provide a descriptive explanation about the validator.
