Incorrect install instructions

[Gregory365]

The issue / experience

The READ.ME links to the wiki, which says to go to java.com to download java, but that is java 8 which is incompatible with the project which uses java 21 (as far as I can tell). Error message: "org/openstreetmap/osmosis/core/Osmosis has been compiled by a more recent version of the Java Runtime (class file version 61.0), this version of the Java Runtime only recognizes class file versions up to 52.0"

What worked

1. Uninstalled whatever current version of java I had using https://www.java.com/en/download/uninstalltool.jsp
2. Installing Java21 JDK from https://www.oracle.com/java/technologies/downloads/#java21
3. Modified the osmosis.bat script in notepad:
4. Changed if defined JAVA_HOME goto findJavaFromJavaHome to goto findJavaFromJavaHome
5. Changed set JAVA_HOME=%JAVA_HOME:"=% to set JAVA_HOME=C:/Program Files/Java/jdk-21
6. Ran the osmisis.bat script (in PowerShell: C:\Program Files\osmosis-0.49.2\bin then .\osmosis.bat)
