Fix tutorial endpoint

Resolves the following issue, which I ran into while testing Unified 1.9.2.rc3 on Chrysalis:

globus_sdk.services.transfer.errors.TransferAPIError: [...] 'GCSv4 is no longer supported. Contact your sysadmin.'

Globus test still seems to be hanging.

Trying #304 (comment):

$ source /lcrc/soft/climate/e3sm-unified/test_e3sm_unified_1.9.2rc3_chrysalis.sh
$ mkdir test_unified_1.9.2rc3
$ emacs setup.sh 
mkdir zstash_demo
mkdir zstash_demo/empty_dir
mkdir zstash_demo/dir
echo 'file0 stuff' > zstash_demo/file0.txt
echo '' > zstash_demo/file_empty.txt
echo 'file1 stuff' > zstash_demo/dir/file1.txt

$ chmod 755 setup.sh
$ ./setup.sh
$ zstash create --hpss=globus://6c54cade-bde5-45c1-bdea-f4bd71dba2cc/~/chrysalis_1.9.2rc3v3 zstash_demo
# Give authentication

Now I'm getting:

It appears I was on the wrong branch or in the wrong directory; the test is now passing.
