[BUG] Cannot build dusty/xtts:r36.4, old XTTS repo is deprecated

[wyhanz]

Thank you for your work on this repository, it has been very helpful to me!

I encountered the following error when attempting to build the dusty/xtts:r36.4 image using jetson-containers:

      Error compiling Cython file:

Upon investigation, I found a similar issue in the original TTS repository issue #4029, which identifies the cause as the old version of the XTTS repository being deprecated and migrated to a new repository idiap/coqui-ai-TTS. It appears that your build scripts still reference a fork of the deprecated version, which could lead to this problem persisting in the future, given that the old repository is no longer supported.

directly clone and then install works for me. (JP61, L4T36.4.0, orin 64GB)

RUN git clone https://github.com/idiap/coqui-ai-TTS ${TTS_PATH} && \
    cd ${TTS_PATH} && \
    pip3 install -e .

Test scripts failed, just skip them.
