This is an interim fix for WT-13607 to remove the CI-blocker status.

When compiling mongo the build artefacts and bazel cache are both saved to the home directory which uses an 80GB disk, but this disk is too small to build mongo.
We need to instead save the output to the /data folder which has significantly more space.

The proper solution is to set bazel config --output_user_root to point at either the /tmp or /data directories, however this produces further build failures. This ticket adds a workaround to soft link the ~/.cache folder to the /data dir, and can be undone when WT-13607 is resolved.
