Fixed double double subscripts in Docs

This is not rendering right in Turing.ml Documentation. See here (https://turing.ml/dev/docs/library/bijectors/#Bijectors.compute_r-Tuple{AbstractVector{var%22#s111%22}%20where%20var%22#s111%22%3C:Real,%20Any,%20Any}). I've tried to corrected it but I don't know if the intent is to signal that α is positive constrained (and y is negative constrained). I would do something like $\alpha^{+}$ (or $y^{-}$).

Ah! Know I get it. The problem is that the bijectors.md for the documentation is kinda hard coded into the jekyll markdown. See here: https://github.com/TuringLang/Turing.jl/blob/master/docs/src/library/bijectors.md

IMO it should be removed completely and be replaced with a proper documentation in Bijectors.

I agree. Thanks for the input.
