What is wrong, less clear, or missing

Environment: Centos 7

Hello.
So i followed this article to install Data Integration.
At the step https://docs.suitecrm.com/admin/suitecrm-analytics/scrm-data-integration/#_installing_suitecrm_data_integration
...when the user is told to execute the script "/setup-suitecrm-data-integration.sh"
...the script exits full of syntax errors

The script starts with "#/bin/sh" which is not even a valid "shebang" (should be #!/bin/sh or #!/bin/bash....as far as i know)
Then, there is the "while" at line 24 which make no sense to me:

        file="./install.properties"

        if [ -f "$file" ]
        then

                while IFS='=' read -r key value
                do
                        key=$(echo "$key" | tr '.' '_')
                        eval '${key}'='${value}'

                done < "$file"

The "eval" command takes its arguments and executes them as a command, so it is expect that the script will exit with errors like

./setup-suitecrm-data-integration.sh: line 27: #: command not found
./setup-suitecrm-data-integration.sh: line 27: SUITECRM_ANALYTICS_WEBAPP_PORT=8080: command not found
./setup-suitecrm-data-integration.sh: line 27: =: command not found
./setup-suitecrm-data-integration.sh: line 27: #: command not found
./setup-suitecrm-data-integration.sh: line 27: SMTP_ENABLED=1: command not found
./setup-suitecrm-data-integration.sh: line 27: #: command not found

$file contains just "key=value" pairs and a few comments and "eval" tries to execute them.

...I would rather assume that i`m missing something and the script is above my understanding than that this "Documentation" is absolutely broken.
Please advice, what am i doing wrong ?

Proposed fixes and/or additions
