Deprecated use of Numpy (np.float) in post-processing corner plot

[MHoogkamer]

Using the PostProcessing.Cornerplot gives the following issue:

AttributeError: module 'numpy' has no attribute 'float'.
`np.float` was a deprecated alias for the builtin `float`. To avoid this error in existing code, use `float` by itself. Doing this will not modify any behavior and is safe. If you specifically wanted the numpy scalar type, use `np.float64` here.
The aliases was originally deprecated in NumPy 1.20;

Can be solved by changing _np.float into float in line 947 in _corner.py

Related to #336

For curiosity, what NumPy version are you using?

And I guess it is the np_.float in line 949 in the current _corner.py of the main branch.

Would you like to fix it?

I'm using NumPy 1.26
