Schedule: Update to reflect upcoming dates

[allyharrison]

The dates need to be updated as per link below

https://www.aicodeaustralia.com.au/#:~:text=South%20Metro%20%2D%2031.07.25,Murdoch%20University

Would also be nice to add images/update styling to look pro

Expected

South Metro - 31.07.25
St Columba's Catholic Primary School

North Metro - 01.08.25
St. Andrew's Grammar School

Award Ceremony & STEM Expo - 02.08.25
Murdoch University

Ideally this would be set up in the database somehow
