it feels a bit odd to introduce a new prop just for this specific sub-state.. I wonder if we can just accept the agent upgrade details information like this:

Suggested change

	status: Agent['status'];
	inFailedUpgradeState: boolean;
	status: Agent['status'];
	upgradeDetails?: Agent['upgrade_details'];

and then use isAgentInFailedUpgradeState() directly in this component to derive the badge. WDYT?

then this component could show other upgrade sub-states in the future if we choose to (I see 9 of them in AgentUpgradeStateType!)
