[5.8] Use custom attributes in lt/lte/gt/gte rules messages

[rgehan]

This PR fixes #29441

Consider these rules:

$rules = [
  'min' => 'numeric',
  'max' => 'numeric|gt:min,
];

And these custom attributes:

$customAttributes = [
  'min' => 'minimum value',
  'max' => 'maximum value',
];

With the following data:

$data = [
  'max' => 10,
];

Validation fails, with the following error message: The maximum value must be greater than min.

It completely ignored the custom attribute defined for max, and the message should be: The maximum value must be greater than minimum value.
