Allow named parameters in t() function calls

Problem/Motivation

PHP version 8+ allow using named parameters in function calls, such as :

// Without named parameters
t('My @string', ['@string' => 'string'], ['context' => 'example context'];

// With parameters
t(string: 'My @string', args: ['@string' => 'string'], options: ['context' => 'example context'];

But sniffers rules do not handle them, and causes a 'Only string litterals should passed to t() where possible' warning.

Steps to reproduce

Call t() or $this->t() with named parameters.

Proposed resolution

I'm guessing the resolution would be something along the lines of the attached patch, which checks token against T_PARAM_NAME, but I'm pretty out of my league here, especially for the tests part.

Remaining tasks

• Confirm validity of proposed solution
• Add tests

I created this issue under feature request, but I'm unsure whether it should be a bug report instead.

Anyway,
Thanks in advance !
