Cesium Inspector Undefined min/max in 1.55

[OmarShehata]

Go to:

https://cesiumjs.org/releases/1.55/Apps/Sandcastle/index.html?src=Cesium%20Inspector.html

Click "Terrain > pick tile", notice the min/max is undefined.

Go to:

https://cesiumjs.org/releases/1.54/Apps/Sandcastle/index.html?src=Cesium%20Inspector.html

Repeat the above, notice the min/max works. Is this a bug in terrain, or does the inspector just need to be updated to account for @kring 's changes?

The inspector just needs to be updated. As part of the terrain overhaul (#7061) the minimumHeight and maximumHeight properties have moved from the QuadtreeTile's data to data.tileBoundingRegion.
To fix it simply add tileBoundingRegion in the missing places:

Another place where it needs to be added is in Globe.prototype.getHeight:

These are the places I found that haven't been updated, there might be some more.

@dennisadams thanks for looking into this! If you have a chance to, it would be awesome to open a PR with this! And then even if there are other places the reviewer might recommend where to look or double check that this is all.
