[Request] Add compatability support for Wikithis

[TheCrossBoy]

The Wikithis mod makes it easy to look for the relevant details for a mod in an instant. Providing support for this would make accessing information about the mod very easy without requiring too much work.

In theory, something along the lines of this should work:

StarlightRiver/Compat/Wikithis/Wikithis.cs

namespace StarlightRiver.Compat.Wikithis
{
    public static class WikithisCall
    {
        public static void CallWikithis()
        {
            if (ModLoader.TryGetMod("Wikithis", out Mod wikithis))
            {
                wikithis.Call("AddModURL", StarlightRiver.Instance, "https://starlightrivermod.wiki.gg/wiki/{}");
            }
        }
    }
}

Having something like this would make playing the mod in its early days much easier! While I know I could make a PR for this, I don't have anything setup for Terraria modding myself and as a non-contributor, I didn't think I should do that.

PS, you've done incredible work so far on the mod. Even in this early state, you've made one of the coolest boss experiences I've had so far, and I'm still early into the content the mod has. Keep up the great work!

Sounds fine, submit a pr!
