use-cache in config is unrecognized #3993
Description
How to reproduce:
<?xml version="1.0" encoding="UTF-8" ?>
<phpdocumentor configVersion="3"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="https://www.phpdoc.org">
<use-cache>false</use-cache>
<title>Foo</title>
<version number="3.0.0">
<api>
<source dsn=".">
<path>src</path>
</source>
</api>
</version>
</phpdocumentor>Error received:
In ArrayNode.php line 327:
Unrecognized option "use_cache" under "phpdocumentor". Did you mean "use-cache"?
It seems to be converting dashes into underscores, and thus, despite providing use-cache it thinks I've passed use_cache.
