fix: Fix float input default value coercion on big integers

[o0Ignition0o]

Fix Float input-type coercion for default values with values larger than 32-bits (Issue #2087)

A regression has been fixed which caused the Router to reject integers larger than 32-bits used as the default values on Float fields in input types.

In other words, the following will once again work as expected:

input MyInputType {
    a_float_input: Float = 9876543210
}
