Budget approval email subject undescriptive for nextgen events

[dd32]

Describe the bug

Budget review request emails subject is bland for nextgen events

Budget Approval Requested: events.wordpress.org

wordcamp.org/public_html/wp-content/plugins/wordcamp-payments/includes/budget-tool.php

Line 122 in ec6fefa

wp_mail( '[email protected]', 'Budget Approval Requested: ' . $domain, $content );

Previously this would've included the actual event, for example:

Budget Approval Requested: 2019.narnia.wordcamp.org (Year.city)

For non-next-gen events it no longer includes the year (Which is ok, since there's only one..)

Budget Approval Requested: narnia.wordcamp.org
