tweak(ext/cfx-ui): allow automated accounts for servers feeds

[TheIndra55]

Goal of this PR

While debugging an issue with a user on the forums, noticed that accounts marked as "Automated" in Mastodon fail to load in the servers feeds. This is because these accounts are returned as type Service in the ActivityPub response, while the code only checks for Person currently.

How is this PR achieving the goal

Allows ActivityPub users with both Person and Service type.

This PR applies to the following area(s)

CfxUI

Successfully tested on

Game builds: N/A

Platforms: Windows

Hmm this could explain why mine doesn't show.

Having one negation for the whole condition would make it more readable in my opinion:

if (!(isObject<IActivityPubAccount>(account) && (account.type === 'Person' || account.type === 'Service'))) {
    throw new Error(`Unknown or invalid account for pub ${this.id}`);
}
