fix(longevity): restore contents of "longevity-mv-si-4days.jenkinsfile"

Commit d722f0d ("test(tier1): Use streaming for
longevity-mv-si-4days.jenkinsfile test", 2024-09-11) intended to do four
things:

(1) create an *unmodified* copy of
    "tier1/longevity-mv-si-4days.jenkinsfile" as
    "longevity/longevity-mv-si-4days.jenkinsfile";

(2) create a *modified* copy of the same
    "tier1/longevity-mv-si-4days.jenkinsfile" as
    "tier1/longevity-mv-si-4days-streaming.jenkinsfile", with the
    modification being the addition of "configurations/disable_rbno.yaml"
    to the test config;

(3) redirect triggers from the original
    "tier1/longevity-mv-si-4days.jenkinsfile" to the modified copy created
    in (2);

(4) remove the original "tier1/longevity-mv-si-4days.jenkinsfile".

Step (1) was implemented incorrectly. The file created in step (1) is not
an *unmodified* copy; today it is identical to the *modified* copy from
step (2).

Restore the actual original contents in
"longevity/longevity-mv-si-4days.jenkinsfile".
