fix JULIA_DEPOT_PATH for Julia

[smoors]

(created using eb --new-pr)

currently the Julia root is appended to JULIA_DEPOT_PATH, which is obviously wrong

workaround until we have a solution for easybuilders/easybuild-framework#4442

@lexming mentioned that using JULIA_LOAD_PATH could be an alternative instead...

[smoors]

it seems that JULIA_LOAD_PATH is only for source code loading, not for compiled code loading.
i did not find any way to load the compiled code using that environment variable.

• here, using JSON loads without precompiling

module load IJulia/1.24.0-Julia-1.8.5
echo JULIA_LOAD_PATH  # :/apps/brussel/RL8/skylake-ib/software/IJulia/1.24.0-Julia-1.8.5

• here, using JSON fails:

unset JULIA_DEPOT_PATH
export JULIA_LOAD_PATH=:/apps/brussel/RL8/skylake-ib/software/IJulia/1.24.0-Julia-1.8.5

• here, using JSON precompiles the JSON package in the default JULIA_DEPOT_PATH, which is not what we want:

unset JULIA_DEPOT_PATH
export JULIA_LOAD_PATH=:/apps/brussel/RL8/skylake-ib/software/IJulia/1.24.0-Julia-1.8.5/packages
