Method explodeExplicitRule working wrong with regex rule

[du-nong-0070]

• Laravel Version: 9.45.1
• PHP Version: 8.1.13
• Database Driver & Version:

Description:

Method explodeExplicitRule works wrong with this rule regex:/^[\d\-]*$/|max:20.

It can not explodes this rule to two patterns like

[
   0 => 'regex:/^[\d\-]*$/',
   1 => 'max:20'
]

I have verified it in Laravel 8 and It has worked perfectly.
I saw Laravel 9 had changed explodeExplicitRule which made it wrong.
In another rule like required|regex:/^[\d\-]*$/|max:20 or just rotate it like max:20|regex:/^[\d\-]*$/,
It works perfectly.
