Light HC theme "prominent" status bar items are low contrast

[Tyriar]

Testing adding a status bar entry in core:

		const statusbarEntry: IStatusbarEntry = {
			name: localize('terminalDevMode', 'Terminal Dev Mode'),
			text: `$(terminal) ${localize('ptyHostStatus.short', 'test')}`,
			// tooltip: localize('nonResponsivePtyHost', "The connection to the terminal's pty host process is unresponsive, terminals may stop working. Click to manually restart the pty host."),
			ariaLabel: localize('ptyHostStatus.ariaLabel', 'test'),
			// command: TerminalCommandId.RestartPtyHost,
			kind: 'prominent'
		};
		this._statusbarService.addEntry(statusbarEntry, 'terminal.promptInput', StatusbarAlignment.LEFT);

Shows this:
