Remove dependabot from "what we've been doing recently..."

[advaithg]

Something I've noticed is that dependabot tends to take over our recent activity a lot of the time, and I think we'd rather highlight people's work than the PRs made by the bot!

One way I can think of doing this is after getting recentEvents from the octokit API in index.tsx, iterate through and remove events with dependabot as the author (you'd have to look into what the API returns to do this). Feel free to implement it however you'd like though - especially if you can think of a more efficient way to do it!
