Display parametric types in a better way?

[ShuhuaGao]

Consider the following two functions in module CGP.

"""
$(TYPEDSIGNATURES)
"""
function fun1(x::AbstractVector{<:Real})
end


"""
$(TYPEDSIGNATURES)
"""
function fun2(x::AbstractVector{T}) where T<:Real
end

The following documentation is produced.

I noticed two issues.

1. The AbstractVector in fun2 becomes AbstractArray again even if I am using Julia 1.6.0. (See How to use alias of AbstractArray instead of the full name? (Feature request) #108)
2. In fun1, the implicit type parameter is an ugly var"#s2". Is it possible to just show the original form x::AbstractVector{<:Real}?

Would be worthwhile just solving these upstream in base Julia rather than trying to work around it here since DocStringExtensions.jl is just, for the most part, utilizing the implementations from Base.

Will be possible make use of #133 to get hold of the actual expression that generates the type and then use that to print something nicer.
