add @maddhruv to calendar maintainers

[maddhruv]

I shall be maintaining the @nodejs/badges and maybe @nodejs/website-redesign meeting events.
Reducing a much load from @bnb 😜

@maddhruv Have you already been given calendar access or is that what we're waiting for before landing this?

[maddhruv]

I don't have access to the calendar right now

[maddhruv]

I still don't have any access to the calendar!
@Trott can you look into?

[Trott]

@Trott can you look into?

I don't think I've ever given calendar privileges to anyone before. Maybe @bnb knows how to do it?

[Trott]

@nodejs/tsc @nodejs/community-committee Anyone know how to the calendar privileges work and feels comfortable extending it to @maddhruv?

[mhdawson]

I figured it out and added him :)

[maddhruv]

Thanks @mhdawson

[maddhruv]

@Trott can this be merged?
