Create live watchlist from tags

This endpoint creates a live watchlist by specifying which tags to monitor:

• When new matching events and markets are created on Polymarket, they will automatically be added to the watchlist if automaticallyAddMatchingEvents is set to true (default).
• When events and markets are closed on Polymarket, they will automatically be removed from the watchlist.

In order to receive alerts when new events and markets are created or existing ones are closed, you can create a New or closed events and markets subscription for the watchlist.
