Update delete account button spacing

[gtsiolis]

Description

Minor spacing change to the delete account button under /account. Seems like a small side effect from the typography components added in #16673.

This will add a ~spacing-scale-3 (1rem/16px) between the heading and the button.

BEFORE	AFTER

Posting for visibility below a screenshot from Foundations / Spacing in the component library in our Figma team, to justify the change.

Spacing Guidelines

gitpod/components/dashboard/src/user-settings/Account.tsx

Lines 93 to 97 in 2d4f946

	<Heading2 className="mt-12">Delete Account</Heading2>
	<Subheading>This action will remove all the data associated with your account in Gitpod.</Subheading>
	<Button type="danger.secondary" onClick={() => setModal(true)}>
	Delete Account
	</Button>
