[Doc]: Update examples script

[forsyth2]

Describe your documentation update

The script at https://e3sm-project.github.io/e3sm_diags/_build/html/master/examples.html#running-the-diagnostics is outdated. Specifically, the node allocation command salloc --nodes=1 --partition=regular --time=01:00:00 -C haswell should be more like salloc --nodes 1 --qos interactive --time 01:00:00 --constraint cpu --account=e3sm, as indicated on https://docs.nersc.gov/jobs/interactive/#perlmutter-cpu-nodes.
