Fix typo in inversion notebook

[rowanc1]

Replace distancee for distance.

Github is saying the outputs changed, which I don't think is true!

This is the intended change:

Thanks @rowanc1. I'm seeing the diff and apparently there were some changes in some outputs:

 1. Because there are no currents in the air, we do not need to pad upwards. I.e. the top of the mesh corresponds to the top of the topography.
 2. We require at least 2-3 cells between each current electrode; with more accurate results being obtained when the minimum cell size is smaller. For a 2.5D problem geometry, we can discretize much finer.
 3. To be safe, the padding thickness should be at least 2-3 times the largest electrode spacing.

[santisoler]

I've pushed changes to revert those modifications to the outputs

[santisoler]

Now I'm merging this 🚀

Thanks for opening this PR!

[rowanc1]

Must have been saving in vscode that changed things, anyhow, glad its sorted!
