Update link_workflow.sh for fix set reorg

- Source new fix.ver file to get fix subfolder version values for setting up fix folder symlinks.
- Change "fix_NEW" to "fix" for FIX_DIR paths: use newly reorganized and versioning fix set.
- Remove "fix_" from /fix folder symlink names.
- Update /fix folder symlink creation to use version variables from fix.ver.
- Update GSI and GDAS fix symlinks.
