Can't import the exported match schedule

**Describe the bug**
When I export the Match Schedule the Break date is not in the same format so this casue isses until you manully fix it (if someone has no idea how to do it, they won't know how to fix it)

**To Reproduce**
Steps to reproduce the behavior:
1. Create Match Schedule with a Break
2. Export it this the file I had :
[lytros_match_schedule.csv](https://github.com/FIRST-Tech-Challenge/scorekeeper/files/15446646/lytros_match_schedule.csv)
3. Try to import it in another event you will get error
4. because the **Break** date was 2024-05-25 but all the **Matchs** has date like this 5/25/2024 and it didn't work until I chaged the break date to be the same as the Matchs date

**Additional context**
We use v5.4.2_offseason
