Refines a query to match items whose specified property value ends with a specified string.
The endsWith() function refines a PublicPlansQueryBuilder to only
match items where the value of the specified property ends with the specified
string. Matching with endsWith() is case-sensitive, so "TEXT" does not end with "ext".
You can only use endsWith() with a property whose value is a String.
The property whose value will be compared with the string.
Supported property: slug
The string to look for at the end of the specified property value.
