Implement dropdown for the list of billing months

[laushinka]

The dropdown was supposed to have been implemented in this ticket.

We could probably use the link dropdown we currently use in the /billing section, right?

gitpod/components/dashboard/src/settings/Billing.tsx

Lines 66 to 83 in 87321b3

	<DropDown
	activeEntry={
	teamsWithBillingEnabled.find((t) => `team:${t.id}` === user?.usageAttributionId)?.name
	}
	customClasses="w-32"
	renderAsLink={true}
	entries={[
	{
	title: "(myself)",
	onClick: () => setUsageAttributionTeam(undefined),
	},
	].concat(
	teamsWithBillingEnabled.map((t) => ({
	title: t.name,
	onClick: () => setUsageAttributionTeam(t),
	})),
	)}
	/>

Thanks for opening this follow-up issue, @laushinka! ✨
