[BUG] Prefix from tailwind.config.js not working with named groups

[bezbac]

Describe the bug
A colleague of mine discovered this issue. We use the ESlint plugin at work and have a shared component library using a tailwind with a prefix to avoid collisions with other tailwind projects. While developing a new feature, we wanted to use the recently introduced syntax for named groups, but ESlint kept nagging about a non-existent class.
I looked into the code for no-custom-classname, and the regex responsible doesn't include the prefix from the tailwind config. I believe this is the issue.

To Reproduce

// HTML
<div class="tw-group/edit">
  <div class="group-hover/edit:tw-text-red-500">Some content</div>
</div>


// tailwind.config.js
/** @type {import('tailwindcss').Config} */
module.exports = {
  prefix: "tw-"
}

The plugin will report a false positive unknown class name tw-group/edit and group-hover/edit:tw-text-red-500

Expected behavior
Support the specified prefix specified inside the tailwind.config.js together with the named groups and peer syntax.
