Type for `broadcast(-, 1:2:∞, 0.3)` changed in Julia 1.8

# 1.8
julia> broadcast(-, 1:2:∞, 0.3) |> typeof
StepRangeLen{Infinities.Infinity, Float64, Int64, Integer}

# 1.7
julia> broadcast(-, 1:2:∞, 0.3) |> typeof
InfiniteArrays.InfStepRange{Float64, Float64}

This breaks some stuff later:

julia> broadcast(-, 1:2:∞, 0.3)
Error showing value of type StepRangeLen{Infinities.Infinity, Float64, Int64, Integer}:

Maybe something has to be overloaded for StepRangeLen as well?

Reproduce the broadcast expression on Julia 1.7 and 1.8, then inspect the StepRangeLen failure at Julia's base/range.jl:940 and the Infinities.Infinity constructors shown in the error. Compare the resulting StepRangeLen with InfiniteArrays.InfStepRange and determine the compatibility point that needs investigation. Done means broadcast(-, 1:2:∞, 0.3) can be evaluated and displayed without the shown MethodError.
