validation

Describe the bug
The isMobilePhone() validator should only validate mobile phone numbers.
Currently it seems that it also validates the local/regional fixed phone numbers.
Reference: https://en.wikipedia.org/wiki/Telephone_numbers_in_Belgium

Examples
Valid ones:

• 0470123456
• +32470123456
• 32470123456

Invalid ones (but valid local/regional fixed phone numbers):

• 02

Bug? I guess.

What is the current behavior?

Package version eg. v9, v10:

github.com/go-playground/locales v0.13.0
github.com/go-playground/universal-translator v0.17.0
github.com/go-playground/validator/v10 v10.2.0

Issue, Question or Enhancement:

Golangci-lint (https://github.com/golangci/golangci-lint) comes with a errorlint linter (https://github.com/polyfloyd/go-errorlint). When I switched it on, I got this issue f

Everything should be updated to validatorjs 13.6.1.

type Item struct {
	Bt int `valid:"range(1|100)"`
}

func main() {
	t := Item{-1}
	ok, err := govalidator.ValidateStruct(t)
	fmt.Println(ok, err)
}

output:Bt: Validator range(1|100) doesn't support kind int;

With #235 I've noticed that InstanceOf is undocumented in the readme.
