./install_mkl.sh error: about kaldi HOT 3 OPEN

My attempt to install kaldi also failed on Fedora 39. It appears that Intel no longer supports this version of MKL; specifically, the package signing keys are no longer valid. I get these error messages:

`extras/install_mkl.sh: Your system is using fedora-style package management.

  Intel currently supports the newer version, renamed oneAPI MKL, available at this URL:
  https://www.intel.com/content/www/us/en/developer/tools/oneapi/onemkl-download.html.

Intel requires one to establish an account (no charge) in order to download and install this library.

Perhaps the developers will be able to substitute the newer libraqry for the old?
