Seasonal Integration

• Rewrote the pack.mcmeta file to allow the datapack to work on future Minecraft Releases! The datapack is now compatible with versions 1.21.1 through to 1.21.10!
• Added the datapacks logo as a pack.png file so it shows up in the datapack selection screen.
• Started using Github to make new versions of the datapack! This means the datapacks license should be included in every release.
• Changed internal ID from "mr_seasonal_integration" to "seasonal_integration"
• Made Blue Wisteria Saplings fertile in Autumn.
• Made White Wisteria Saplings fertile in Winter.
• Made Purple Wisteria Saplings fertile in Summer.
