Would it just turn into a pressurized container full of steam? Would the water stay water but just like, really hot?

The boiling point of water isn’t always 100°C it depends on the pressure. This is why water boils at a lower temperature at higher elevations. And since it’s a sealed container and the water wants to expand as it’s heated, the pressure increases as you heat the water.

So in the red, it would be a liquid, and in the green it would be a gas. Beyond the critical point, there’s no difference between a liquid and gas, so it’s called a supercritical fluid.
You can also see that if you lower the pressure, the water will begin to spontaneously boil. If you get things just right, you’ll hit the triple point where the water is stable as a gas, liquid and solid all at the same time and can see boiling water with an ice cube floating in it
