You use short-term debt as well. The reason being that Enterprise Value, as stated before is essentially the total cost to take over the firm. Total cost to take over the firm includes the entire market cap, and all the debt you have to pay off. Whether the debt is short-term or long-term you still have to pay it off so it should be included in the EV calculation.
Side note: Make sure to also subtract cash/cash equivalents/marketable investments from EV as those accounts reduce your total cost for taking over the company
