torch>=2.4 dependency in dev means no support for Intel Macs

[ajkessel]

Describe the bug

torch stopped building for Intel Macs after 2.2.2. coqui-tts main branch still installs because it only requires torch>=2.1, but on dev you are requiring torch>=2.4, and thus it cannot be installed even on a relatively recent Mac (e.g. iMac (Retina 5K, 27-inch, 2020)). Do you need the >=2.4 requirement or could it be loosened?

To Reproduce

Yeah, I agree it's not ideal. I've started adding some conditional handling for the code that needed this in idiap/coqui-ai-Trainer#11, after which I can do the same in this repo (#113) and go back down to 2.1

[eginhard]

The minimum Pytorch version is now back to 2.1 (2.3 if using Python 3.12).
