Load tips title text and other strings from JSON file instead of being hardcoded

[drojf]

Currently, the tips menu text is hardcoded:

See this line of code: https://github.com/07th-mod/higurashi-assembly/blob/matsuri-mod/Assets.Scripts.UI.Tips/TipsManager.cs#L69

It would be better to load it from the tips.json file (if the field exists, to keep compatibility with older tips.json files)

I need to make some other changes to the DLL - this fix can be bundled with it.

I've added a feature where the mod can load strings from a localization.json file.

However, I still need to go through the chapters which have the tips menu text and add a function call to get the text from the localization.json. (Mainly becuase I forgot to do this earlier...)

I've decided to keep this separate from the tips.json file since these strings are not specific to tips/don't get unlocked at certain times etc.

The format is like this:

{
    "allChapters":
    {
        "no-tips-available" : {
            "comment": "This text appears at the top of the tips menu when there are no tips available",
            "text": "No new tips available",
            "textJP": "入手ＴＩＰＳはありません"
        }
    }
}

Which is deserialized into the following C# class (can add more fields later):

public class LocalizationEntry
{
    public string comment;
    public string text;
    public string textJP;
}

public class LocalizationInfo
{
    public Dictionary<string, LocalizationEntry> allChapters;

    public LocalizationInfo()
    {
        allChapters = new Dictionary<string, LocalizationEntry>();
    }
}

Some translation teams have translated the mod menu (F10 menu) text - these texts should be added to the localization.json file.
