Changes

• Changes the validateNumeric in ValidatesAttributes trait to accept a strict parameter.
• Updated uses of validateNumeric in other validation methods to provide the new parameter.
• Adds a test for the change.

Why

Same purpose as #56313. This would allow for blocking strings being used in JSON requests for numbers e.g. allow 1 but not '1'. This is useful for APIs where allowing strings might not be what the end user wants compared to web forms that are more flexible when it comes to strings.

$v = new Validator($trans, ['foo' => '1'], ['foo' => 'Numeric:strict']); // fails
$v = new Validator($trans, ['foo' => 1], ['foo' => 'Numeric:strict']); // passes

Notes

I've kept this to just numeric as that will work with both floats and integers rather than applying this parameter to the wide range of number based options.
