Update pycolmap documentation from rmbrualla to trueprice.

[humberthardy]

In the documentation, it is mentioned that we can use fisheye camera model, but you probably forgot to mention that we should use another version of pycolmap, trueprice, because:

1. rmbrualla does not support OPENCV_FISHEYE camera model

2. rmbrualla's commits has been already merged to trueprice (-rmbrualla is a fork of trueprice-)

   Tip for testers: do not forgot to update the Config.near if you are using a fisheye camera ;)

@humberthardy If using OPENCV_FISHEYE, what's the value of Config.near should setting?

@hecodeit: I notice we had a kind of "sphere removal" with fisheye around the camera (like the teleporter in terminator). My pictures were not blurred, so I used a value close to 0 (0.001 if I remember well)

Thanks @humberthardy, I'll try 0.001

I notice NerfStudio most dataset use fisheye lens, and the near plan setting using 0.05, maybe try 0.05 both.
