binomial of two symbolics no longer works on 1.10

[isaacsas]

This previously worked (and is used in Catalyst for jump process models):

using ModelingToolkit
@parameters a
@variables t A(t)

# still works
binomial(A, 2*a^2)

# no longer works, but is used internally in Catalyst for example:
binomial(Symbolics.value(A), Symbolics.value(2*a^2))

What if you change @register_symbolic Base.binomial(n, k)::Int true [Integer] to @register_symbolic Base.binomial(n, k)::Int true [Integer, Real]?

I'll check.
