Use new lighter taskProcessingManager::getAvailableTaskTypeIds method

[julien-nc]

Use new lighter taskProcessingManager::getAvailableTaskTypeIds() method to check which feature is available.

When calling taskProcessingManager::getAvailableTaskTypes() the manager gets a full description of the task types. This description includes some data that is provided by the preferred providers for the task types like the default values and the multiselect values. Those values are cached but when there is no cache hit (task processing cache and provider-specific cache), some of them are obtained with a network request (like the model list in integration_openai). So if one just needs to know the list of available task types without any extra detail, one can now use taskProcessingManager::getAvailableTaskTypeIds() which returns a list of strings and does not get any extra info from the providers.

This method is fairly recent so it's not included yet in nextcloud/ocp. Should we adjust the psalm baseline or wait until nextcloud/ocp is up-to-date? Or even ignore the psalm failure?

This can be backported to stable32 as the new method is there. See nextcloud/server#54917 and nextcloud/documentation#13608

Nice! Let me see what can be done about ocp.

Backporting it seems like a good idea from a performance perspective.
