Update the Plugin Manager Flatpak loader data path to match the Flatpak third party plugin merge-dir.

Description

Currently, the plugin manager attempts to load plugin data for Flatpak distributed plugins from an incorrect location. The OBS Flatpak manifest states that plugins should store their data at:

/app/plugins/share/obs/obs-modules/plugins/<PLUGIN_NAME>

but the plugin manager was attempting to load data from:

/app/plugins/share/obs-modules/plugins/<PLUGIN_NAME>

This PR updates the loading path to include the missing obs/ subdirectory.

Motivation and Context

Without this change, it is not possible for Flatpak plugins to be loaded using the new plugin format.

How Has This Been Tested?

I did a quick test on a local Flatpak build to make sure this works properly, and it does. I was not able to test the actual live Flatpak OBS currently on Flathub.
