[develop]: Update for Gaea software stack location and Lmod initializ…

…ation script (#627)

* Gaea hpc-stack location has changed to match that for the UFS-WM that results in all regression test passed successfully.
* Lmod initialization has been updated as well, similar to the one that worked for the UFS-WM to pass RTs. It is done by sourcing a single initialization script.
