Opt-out for emails on PR merge

[tomer-ds]

Is your feature request related to a problem? Please describe.
I am getting spammed by emails now on every merge of updated changelog PR.
This will cause an issue in our entire organization.
The need is understandable, but I feel there should be an opt-out configuration

Describe the solution you'd like
An option to disable emails from github sent from the action

Describe alternatives you've considered
I really don't like the other changelog actions... yours is concise and easy to use... others are complex and over engineered.
Essentially I am not looking for an alternative... just to help you improve this tool 🥇

Additional context

I don't think there is any option for a GitHub Action to suppress GitHub E-mail Notifications (E-mails are not sent by the Action rather sent by GitHub on state changes to the repository). You probably need to adjust the watch settings or other notification options.
