The EU VAT App label on checkout misses the VAT Rate

When the EU VAT app is enabled, the VAT indication label on the checkout looks like this:

It would be much clearer to the user if they can see the actual VAT rate like this:

To make your life easier, I am including below the changes need to be done:

1. Update the COM_PAYPLANS_APP_EU_VAT_MODIFIER_MESSAGE language string in administrator/components/com_payplans/languages/site/en-GB.com_payplans.ini

COM_PAYPLANS_APP_EU_VAT_MODIFIER_MESSAGE="EU-VAT Tax added"

with

COM_PAYPLANS_APP_EU_VAT_MODIFIER_MESSAGE="EU-VAT Tax added %d%%"

2. Update plugins/payplans/euvat/app/euvat.php line 39:

$tax->title = JText::_('COM_PAYPLANS_APP_EU_VAT_MODIFIER_MESSAGE');

with

$tax->title = JText::sprintf('COM_PAYPLANS_APP_EU_VAT_MODIFIER_MESSAGE', $tax->rate);
