Java↔Bedrock Seed Conversion

Before 1.18, Java and Bedrock seeds are not equivalent and cannot be converted across editions.
In versions 1.18 and above, Java and Bedrock seeds are mostly identical.
To convert a Java seed to Bedrock or vice versa, simply use the exact same seed in the world creation menu.
