Jenkins file point to 1.3 branch temporarily instead of main

[IanHoang]

Description

Pushed patch release from new 1.3 branch but Jenkins is running into following error:

#14 [linux/amd64 4/6] RUN if [ -z "1.4.0" ] ; then python3 -m pip install opensearch-benchmark ; else python3 -m pip install opensearch-benchmark==1.4.0 ; fi
#0 1.734 ERROR: Ignored the following versions that require a different python version: 0.0.1 Requires-Python >=3.8,<3.10; 0.0.2 Requires-Python >=3.8,<3.10; 0.1.0 Requires-Python >=3.8,<3.10
#0 1.735 ERROR: Could not find a version that satisfies the requirement opensearch-benchmark==1.4.0 (from versions: 0.2.0, 0.3.0, 0.4.0, 0.4.1, 0.5.0, 1.0.0, 1.1.0, 1.2.0, 1.3.0, 1.3.1)

We need to update jenkins file to point to 1.3 instead of main as a quick workaround. In the future, we should have a way where the Github Actions can take a "branch" parameter so that main isn't the only branch we can push releases from.
