Legacy devPlugins directory support removed

Lali-ho! Hope you're staying cozy after the big patch.

Following up on goat's previous announcement from June 2022, we are removing support in Dalamud for loading plugins from the legacy devPlugins directory, which was already deprecated for quite some time. To load plugins for development, you'll need to add a dev plugin path in your Dalamud settings.

We understand that this change will probably have impacts on the experience of ad-hoc user testing, but its removal should significantly reduce support burden from unintentional use of this legacy directory, especially post-6.4. We're continuing work on making ad-hoc testing with users easier going forward as well, and of course are always open to feedback!

Thanks for your hard work on plogons, and see you next time! 🐴 ✨
