Edit icons: 3x3/OH/BLD Relay and Team Relay, 3x3 BLD 4/8-man Relay and Mini Guildford

[dmint789]

This PR edits the following icons:

1. Mini Guildford
2. 3x3 BLD 4-man Relay
3. 3x3 BLD 8-man Relay
4. 3x3 + OH + BLD Relay
5. 3x3 + OH + BLD Team Relay

All changes except Mini Guildford are simple tweaks based on actually using the new icons. Mini Guildford includes the following changes:

• Reposition the elements to respect padding
• Make the OH event consistent with the 333oh icon

• Use the Clock's handle, since it doesn't add too much detail, while making it clear this is the Clock event

Oops, I accidentally closed this while trying to merge (forgetting that I don't have the rights). @jfly can you merge this?

@jfly could you also please deploy this? 🙏

@dmint789, we don't really deploy this anywhere. Are you asking for me to do a release?

[dmint789]
