Bug:

[SunilEver]

Describe the bug
$validationMessages fields on CodeIgniter\Model is an overkill. One can always set error messages on $validationRules using errors key

CodeIgniter 4 version
v4.0.0-rc.3

Affected module(s)
Codeigniter\Model

Context

• OS: Ubuntu 5.4.0-6ubuntu1~16.04.12
• Web server: php inbuilt server
• PHP version : 7.3

$validationMessages allows errors to be set on-the-fly by the setValidationMessages() method, allowing Controllers to provide their own messages that would not ordinarily be available if using the errors key in $validationRules.
