Add explicit Core/24.00 module to Frontier

[grnydawn]

Explicitly load the Core/24.00 module to prevent the new default Core/24.07 module from loading on Frontier. NOTE: E3SM-Project/scream#3029

Ran a subset of e3sm_developer tests, which showed similar results to previous tests.

BFB (no reference on Frontier).

@rljacob , @jgfouca , The new default Core/24.07 module on Frontier causes issues due to the mismatching of several utility modules, including Subversion, Git, Darshan-runtime, and CMake, which ultimately breaks the E3SM build on Frontier. @trey-ornl also warned that the new CMake might have difficulty with the older style of handling Cray and AMD compilers. Following @trey-ornl's recommendation, I have explicitly added Core/24.00 in config_machines.xml.

Is it conflicting with these lines?

        <command name="load">subversion/1.14.1</command>
        <command name="load">git/2.36.1</command>
       <command name="load">cmake/3.21.3</command>

I don't think we need those specific versions of git and subversion so just take them out and let Core/24.07 load what it wants.

Not sure what to do about cmake. What version is Core/24.07 trying to load? Also where do we load darshan? Its not an explicit load command.

darshan-runtime gets loaded by default.

The only CMake available with Core/24.07 is cmake/3.27.9, and this broke the crayclang-scream build for me in the "scream" repo (but not the shiny new craygnuamdgpu build).

I tried building E3SM with the new Core/24.07 module after removing the versions from those load commands, and it seemingly solved the build issue without any error message. I have not yet completed the tests up to running a case, but I believe this issue likely affects the build phase, not the runtime.

I will test more cases, and if all tests show no this type of issue, I plan to drop this pull request and create a new one without the versions for the util modules.

The issue with Core/24.07 may be specific to crayclang-scream, which keeps old versions of the Cray software to match what the decadal run started with.
