[BUG] Extension is not visible inside extension-dropdown

[PKuhlmay]

I added my custom sitepackage and this was not shown inside the dropdown for selecting the host extension.
Reason could be

content-blocks-gui/packages/content_blocks_gui/Classes/Utility/ExtensionUtility.php

Line 59 in c2900d3

continue;

The extension is not added, when it has no require-dependency for content blocks in its composer.json.

This should not happen, as we can not be sure if everybody has this dependency set. For example, if you have a composer.json for the whole project, and the dependency is set there, but not in the sitepackage.

Suggestion: Search for local packages like content blocks does.
