Update miniconda and pyfmi

[dhblum]

When building the test case Docker container, solving the environment for installing pyfmi 2.11 is taking a while (on the order of 10-15 minutes). I'm not totally sure the reason for this as it hasn't been an issue in the past, but I've noticed it recently with some local testing and with it starting to cause unit test failures due to timeouts, as here: https://app.travis-ci.com/github/ibpsa/project1-boptest/builds/270377300.

pyfmi 2.12 has recently been released and experimenting with using it, along with updating the miniconda installation used in the Docker container, seems to significantly speed up the environment solving and overall installation process to a reasonable point.

So, this issue will update:

• pyfmi from 2.11 to 2.12
• miniconda from py310_23.1.0-1-Linux-x86_64 to py310_24.3.0-0-Linux-x86_64
