Swan.Formatters.Json class sometimes serialize double as string

[mayorovad]

Describe the bug
Serializing double value to JSON using Swan.Formatters.Json class sometimes results in string in exponential form.

To Reproduce

using Swan.Formatters;
using System.Text.Json;

List<double> doubleValues = [1, 5e-5];

var swanRes = Json.Serialize(doubleValues);
var textJsonRes = JsonSerializer.Serialize(doubleValues);

Console.WriteLine($"SWAN: {swanRes}");
Console.WriteLine($"Text.Json: {textJsonRes}");

results in

SWAN: [1,"5E-05"]
Text.Json: [1,5E-05]

Expected behavior

SWAN: [1,5E-05]
Text.Json: [1,5E-05]
