Fix JSON deserialization crash by adding JsonStringEnumConverter

[Copilot]

Mod crashes on load with JsonException when deserializing Crops.json because System.Text.Json cannot convert string enum values without explicit configuration.

Changes

• Added JsonStringEnumConverter to deserialization options in LoadBaseGameCrops()
• Added using System.Text.Json.Serialization directive

var options = new JsonSerializerOptions
{
    Converters = { new JsonStringEnumConverter() }
};
var list = JsonSerializer.Deserialize<List<Crop>>(json, options);

This allows the deserializer to convert "spring" → Season.spring for the Seasons property.

Pull Request Overview

This PR fixes a critical crash on mod load caused by System.Text.Json being unable to deserialize string enum values without explicit configuration. The fix adds JsonStringEnumConverter to enable proper conversion of season strings (e.g., "spring") to their corresponding Season enum values.

• Added JsonStringEnumConverter to deserialization options in LoadBaseGameCrops()
• Added the required using System.Text.Json.Serialization directive

@copilot Does this fix need to be applied to loading crop files for other mods?

@copilot Does this fix need to be applied to loading crop files for other mods?

No, the fix is not needed for loading mod crops. The FromModFile() method in Crop.cs uses a different approach - it parses JSON with JsonNode.Parse() and manually converts strings to Season enums using Enum.TryParse<Season>(s, ignoreCase: true, ...) (lines 112, 128). This already handles string-to-enum conversion correctly without requiring JsonStringEnumConverter.
