Add EvoLinear.jl to model registry

[jeremiedb]

I'd like to have EvoLinear.jl added to the model registry. MLJModelInterface is integrated starting with version v0.3.0.

THe library currently essentially covers the the gblinear from XGBoost, that is, linear booster with L1/L2 regularization. on 1M x 100 feats, EvoLinear.jl is typically over 2X faster than XGBoost equivalent.

Nice. This is happening about once a week these days as part of docstring updates, so it'll get done then.
