start.sh creates an unusable path to java

[Goobaroo]

When using the serverinstaller on linux. (build 22.530.1936).

The start.sh script incorrectly adds a "./" to the path to both the JVM when chosen to install with the server

.//data/jre/jdk-17.0.2+8-jre/bin/java -javaagent:log4jfix/Log4jPatcher-1.0.0.jar -XX:+UseG1GC -XX:+UnlockExperimentalVMOptions -Xmx6144M -Xms4096M @user_jvm_args.txt @libraries/net/minecraftforge/forge/1.18.2-40.1.25/unix_args.txt nogui

If you skip the JVM install you get:
./java -javaagent:log4jfix/Log4jPatcher-1.0.0.jar -XX:+UseG1GC -XX:+UnlockExperimentalVMOptions -Xmx6144M -Xms4096M @user_jvm_args.txt @libraries/net/minecraftforge/forge/1.18.2-40.1.25/unix_args.txt nogui

I noticed that it is now deleting the run.sh that is provided by Forge. But you can retain it by using the --noscript flag which produces a usable run.sh/bat that you can use to start the server.

Seems related to this change here:

"./" + java.GetJavaPath(installPath) + " -javaagent:log4jfix/Log4jPatcher-1.0.0.jar " + launch
