Add generator syntax as DimArray method

[kapple19]

Instead of rebuilding an array comprehension that generates a DimArray to e.g. name it, this allows the cleaner syntax:

julia> DimArray((x, y) for x in X(10:10:50), y in Y(0.0:0.1:1.0); name = :Value)
╭──────────────────────────────────────────────╮
│ 5×11 DimArray{Tuple{Int64, Float64},2} Value │
├──────────────────────────────────────────────┴───────────────────────────────────────────────────────── dims ┐
  ↓ X Sampled{Int64} 10:10:50 ForwardOrdered Regular Points,
  → Y Sampled{Float64} 0.0:0.1:1.0 ForwardOrdered Regular Points
└──────────────────────────────────────────────────────────────────────────────────────────────────────────────┘
  ↓ →  0.0         0.1         0.2         0.3         …  0.7         0.8         0.9         1.0
 10     (10, 0.0)   (10, 0.1)   (10, 0.2)   (10, 0.3)      (10, 0.7)   (10, 0.8)   (10, 0.9)   (10, 1.0)        
 20     (20, 0.0)   (20, 0.1)   (20, 0.2)   (20, 0.3)      (20, 0.7)   (20, 0.8)   (20, 0.9)   (20, 1.0)        
 30     (30, 0.0)   (30, 0.1)   (30, 0.2)   (30, 0.3)      (30, 0.7)   (30, 0.8)   (30, 0.9)   (30, 1.0)        
 40     (40, 0.0)   (40, 0.1)   (40, 0.2)   (40, 0.3)      (40, 0.7)   (40, 0.8)   (40, 0.9)   (40, 1.0)        
 50     (50, 0.0)   (50, 0.1)   (50, 0.2)   (50, 0.3)  …   (50, 0.7)   (50, 0.8)   (50, 0.9)   (50, 1.0)

I've added to the documentation that the semi-colon ; is required to distinguish between the generator syntax dimensions and the keyword arguments.

Is the nightly error my fault?

I imagine not, it's failing on my PR as well.
