Organise sponsor perks at the SR2025 competition

[github-actions]

As part of the sponsorship packages we offer, we need to provide various perks to our sponsors. This task covers the organisation of those perks in the context of the competition.

These include:

• a brief overview in the booklet
• an invitation to the competition
• their logo on banner
• a mention in the prize-giving
• their name on an award

Required actions:

• Send an email to get a logo for the booklet/banner/shirt
• Send an email to get their preferences for award to sponsor
• Send an email to invite the sponsors to the competition

Note: some of these emails can probably be combined

Most of the sponsor perks have been covered, but I think we may still need to do the shout-outs on social media (cc @sedders123)
