Remove Snapshot datetime format is incorrect

[HeartofPhos]

Describe the bug
The format provided to moment.js in ExilenceNextApp\src\components\remove-snapshots-dialog\RemoveSnapshotsDialog.tsx:100 is incorrect, the given format is 'YYYY-MM-DD HH:MM' instead of 'YYYY-MM-DD HH:mm' resulting in the month of the snapshot being rendered in the minutes positions

To Reproduce
Steps to reproduce the behavior:

1. Take at least 1 snapshot
2. Open then Remove Snapshots dialogue
3. Observe the minutes value is equal to the current month and not the minutes of the snapshot
