docs: fix link to an example file
Relative links within the source tree work, but they were not being
turned into nice usable hyperlink that go back to GitHub under the
generated documentation.

1. ``'type_def': 'variable_gain'`` is a simplified model simulating a 2-coil EDFA with internal, input and output VOAs. The NF vs gain response is calculated accordingly based on the input parameters: ``nf_min``, ``nf_max``, and ``gain_flatmax``. It is not a simple interpolation but a 2-stage NF calculation.
2. ``'type_def': 'fixed_gain'`` is a fixed gain model. `NF == Cte == nf0` if `gain_min < gain < gain_flatmax`
-3. ``'type_def': None`` is an advanced model. A detailed JSON configuration file is required (by default `gnpy/example-data/std_medium_gain_advanced_config.json <gnpy/example-data/std_medium_gain_advanced_config.json>`_). It uses a 3rd order polynomial where NF = f(gain), NF_ripple = f(frequency), gain_ripple = f(frequency), N-array dgt = f(frequency). Compared to the previous models, NF ripple and gain ripple are modelled.
