v3.19.1 - Holidays edition

I hope everyone had a great Christmas 🎄 and I wish all an incredible 2023 as well 🌟 🎆

This release includes mostly small bug fixes, but it also included support to the brand new --json flag.

---

• Small bug fix: closing Taskfile.yml once we're done reading it (#963, #964 by @HeCorr).
• Fixes a bug in v2 that caused a panic when using a Taskfile_{{OS}}.yml file (#961, #971 by @pd93).
• Fixed a bug where watch intervals set in the Taskfile were not being respected (#969, #970 by @pd93)
• Add --json flag (alias -j) with the intent to improve support for code editors and add room to other possible integrations. This is basic for now, but we plan to add more info in the near future (#936 by @davidalpert, #764).
