With every fork bitcoin supply is increasing

No. The supply stays the same. A fork is introducing a new client and new coin.

An accurate way to phrase the limit is that the current main chain will never have more than 21 million coins. While a new fork may become the main chain, anyone who wishes to preserve the 21 million limit can continue using the chain with the previous (and arguably correct) supply.
