Some "View on github" links return "page not found" or direct to lines different from the source function.

To Reproduce
I tested three links:

For pvsystem.v_from_i the "View on github" link directs to these lines in the max_power_pt function.

For pvsystem.max_power_point the "View on github" link directs to these lines.

For ivtools.sdm.pvsyst_temperature_coeff the "View on github" link returns page not found.
