Plugin Directory: Allow 'for-X-and-TRADEMARK' pattern in plugin names

[davidperezgar]

This update extends the trademark validation logic to support plugin names following the pattern "for-{service}-and-{trademark}", in addition to the existing "for-{trademark}" pattern.

This allows more natural plugin naming for integrations that connect multiple services, while still maintaining trademark protection requirements.

Examples of now-allowed names:

• "Integration for Service-X and WooCommerce"
• "Payment Gateway for Provider-Y and WooCommerce"
• "Connector for Platform-Z and WooCommerce"

The following patterns remain blocked (as expected):

• "WooCommerce Integration" (trademark at start)
• "My WooCommerce Extension" (trademark in middle)
• "Service and WooCommerce" (missing 'for' keyword)

All existing trademark validations remain intact and functional.
