Update creating-your-first-script-csharp.md

[SQKo]

Add a client-specific ClientScript and server-specific ServerScript class as alternative to BaseScript, which was added since artifact 3395 citizenfx/fivem@304f787

This looks good to me, sorry for the super late response. Perhaps you could provide some usage example? :-)

[SQKo]

There is no example actually, unless you want me to replace "BaseScript" with "ClientScript"/"ServerScript" in examples of another pages,

which I found here: https://github.com/citizenfx/fivem-docs/blob/cd7acf5402b61feda988f521c98f46aaa3541617/content/docs/scripting-manual/introduction/creating-your-first-script-csharp.md

using CitizenFX.Core;

namespace MyResourceNameClient
{
    public class Class1 : BaseScript
    {
        public Class1()
        {

        }
    }
}

becomes:

using CitizenFX.Core;

namespace MyResourceNameClient
{
    public class Class1 : ClientScript
    {
        public Class1()
        {

        }
    }
}

As far I know this was added only to prevent possible ambiguity/conflict when building and linking the .dll

This should probably be explained better within the example, given the age of this PR I'm going to close this and add it to the tracking issue #466
