Integration loader does not respect "provided" plugins

[NonSwag]

Describe the bug
Plugins that are not officially supported but provide a supported plugin (for example, Vault) are not detected as available hook

To Reproduce

1. Install a plugin like ServiceIO (provides Vault)
2. Start the server and wait for the log [eco] Loaded integrations: ...
3. Look for Vault (not there)

Expected behavior

Because the plugin is not, but does provide vault, it should be used as dependency

Server Information:

• Version: Paper 1.21.1
• Version of eco: 6.74.3

Additional context

eco/eco-api/src/main/java/com/willfp/eco/core/integrations/IntegrationLoader.java

Line 20 in be970bd

private static final Set<String> LOADED_PLUGINS = Arrays.stream(Bukkit.getPluginManager().getPlugins())

Adding all entries from PluginDescriptionFile#getProvidedPlugins (or for paper PluginMeta#getProvidedPlugins) would solve this issue
