Unable to install more than 1 errata via command `hammer job-invocation create --inputs` using either key=value pairs or valid json

Version-Release number of selected component (if applicable):
satellite-6.13.1

How reproducible:
Every time

Steps to Reproduce:
1. Register a system to a Satellite with 2 or more errata that are installable
2. Try to install 2+ errata using the --inputs option
3.

Actual results:
Only installs 1 of the listed errata

Additional info:
Workaround:
Adding the list of errata to a text file, comma separated, no spaces like:
RHBA-2023:0001,RHSA-2023:0002,RHEA-2023:0003
and referencing that file using the option '-input-file' in place of '-inputs' like the following:
--input-files "errata=/tmp/test.txt"

Full example:

1. cat /tmp/test.txt
   RHBA-2023:1989,RHBA-2023:3486

1. hammer job-invocation create --feature katello_errata_install --search-query "drone79.usersys.redhat.com" --input-files "errata=/tmp/test.txt"

//From the template rendering we can see that the yum command being passed to the client is as follows:
--------------
#!/bin/bash

1. Helper function that exits with a particular message and code.
   #
2. Usage:
3. exit_with_message "Could not do a thing" 2
   #
   exit_with_message () {
   echo "${1}, exiting..."
   exit $2
   }

1. Action
   yum -y update-minimal --advisory="RHBA-2023:1989 --advisory=RHBA-2023:3486"
   RETVAL=$?
   [ $RETVAL -eq 0 ] || exit_with_message "Package action failed" $RETVAL
