Fixes incorrect cast of parameters in CommandBuilder

[gehongyan]

Description

In CommandBuidler, the AddParameters expects an array of TParamBuidler.

Discord.Net/src/Discord.Net.Interactions/Builders/Commands/CommandBuilder.cs

Lines 136 to 147 in de8da0d

	/// <summary>
	/// Adds parameter builders to <see cref="Parameters"/>.
	/// </summary>
	/// <param name="parameters">New parameter builders to be added to <see cref="Parameters"/>.</param>
	/// <returns>
	/// The builder instance.
	/// </returns>
	public TBuilder AddParameters(params TParamBuilder[] parameters)
	{
	_parameters.AddRange(parameters);
	return Instance;
	}

In the explicit implementation of ICommandBuilder.AddParameters, the parameters of type IParameterBuilder[] should be cast to TParamBuilder[] array instead of a single TParamBuilder.

Discord.Net/src/Discord.Net.Interactions/Builders/Commands/CommandBuilder.cs

Lines 186 to 188 in de8da0d

	/// <inheritdoc/>
	ICommandBuilder ICommandBuilder.AddParameters(params IParameterBuilder[] parameters) =>
	AddParameters(parameters as TParamBuilder);
