Adoptium Summit - Webpage Updates (LOGO UPDATE, PC, SPEAKER, AGENDA...)

Hey Team,

I'm creating this issue per Olivier's request for all future updates to the Adoptium website that is needed from our WEbdev Team. The document can be found below and I will update this issue when we receive some information as it comes in so you are notified. It will be highlighted both on the document and this comment section.

thank you again for all your help. https://docs.google.com/document/d/1AkBgjjIcZQA4VBWnKtZd8i32JLcUC3xfmyc_xdaMK7w/edit?usp=sharing
