Fix convert([v], v) dispatch for Julia 1.10

[etpinard]

fixes #228

---

This is crucial for CallbackDeps instantiation

Dash.jl/src/app/supporttypes.jl

Lines 88 to 96 in 462b215

	struct CallbackDeps
	output ::Vector{<:Output}
	input ::Vector{<:Input}
	state ::Vector{<:State}
	multi_out::Bool
	CallbackDeps(output, input, state, multi_out) = new(output, input, state, multi_out)
	CallbackDeps(output::Output, input, state = State[]) = new(output, input, state, false)
	CallbackDeps(output::Vector{<:Output}, input, state = State[]) = new(output, input, state, true)
	end

I'm not sure why the Julia <=1.9 dispatch fails in Julia 1.10.

It seems that Julia 1.10 is more strict about element types during conversion to Vector.

In 1.9

but in 1.10

Any help on this topic would be much appreciated.
