Feature: #106072 - Introduce regex based replacements for slugs

Description

Adds a second replacement config array to provide regex based definitions. This way it's possible to define case-insensitive or wildcard replacements.

Note

The regexp based replacement operates on the original field values, which are not sanitized yet. That means, not lowercased or otherwise processed and only on field level for the record configured with the ['generatorOptions']['fields'] option. Additional, not automatic character detection and escaping is processed and needs to be taken care when configure patterns. Keep these points in mind.

Impact

Slug fields have now a new regexReplacements configuration array inside generatorOptions.

'generatorOptions' => [
  'regexReplacements' => [
      '/foo/i' => 'bar', // case-insensitive replace of Foo, foo, FOO,... with "bar", ignoring casing
      '/\(.*\)/' => '',  // Remove string wrapped in parentheses
      '@\(.*\)@' => '',  // Remove string wrapped in parentheses with custom regex delimiter
   ],
],
