FFTLog example in docs not reproducible

[MartinKaercher]

Hi hankl-Team,
I am currently working on my own FFTLog implementation and I wanted to compare my code with your package.
When I copy the code from the docs where the function k*np.exp(-k**2 / 2) is transformed I found that I am not getting exactly the same as in the docs, the behaviour at low-k is different and differs more from the analytical expression.
I have appended a plot with the visible feature.
I am running Python 3.9.7 on a Mac with numpy 1.26.3 and hankl 1.1.

As a side-note: I think there is a small typo in the example code in the docs ax2.yaxis.set_label_position("left") should be ax1.yaxis.set_label_position("left") I think, as ax2 is not yet defined at that point and would raise an error.
Thanks for your help!
Cheers,
Martin
