Temporary or action-related disabled translator-notifications

### Describe the problem

I am project owner (but not admin) on translate.codeberg.org.

My workflow might be unusual but I do sync the weblate repo and my upstream repo manually. At the end I always press "Reset and discard" to in the maintenance section of Weblate.

It seems that all translators are notified via email about that. It is sometimes a bit to noise depending on how often I do sync the project like that.

### Solution brainstorm

I would like to have the option to disable any notification email a) while doing this action (reset and discard) or b) for a specific time period.

### Describe alternatives you have considered

Maybe the easiest would be to just offer an "Disable all user/translator notifications" button.

In this case I am responsible myself. I need to remember to push that button before using "Reset and discard" and push it again after it.

### Additional context

_No response_

Start at the maintenance section's "Reset and discard" action and trace how it triggers translator email notifications. Compare the requested temporary, action-scoped, and global disable alternatives before choosing a scope. Done means the selected option prevents those notifications without disrupting the reset-and-discard workflow.
