Can't debug Gradle process

I'd love to be able to use this plugin to debug Gradle plugins and processes spawned by Gradle.

Unfortunately, after running `source ~/.attachme/conf.sh` all Gradle tasks fail with the output:

```shell
* What went wrong:
Unable to determine version for JDK located at /Library/Java/JavaVirtualMachines/adoptopenjdk-15.jdk/Contents/Home. Reason: Unexpected command output:
Listening for transport dt_socket at address: 53880
/Library/Java/JavaVirtualMachines/adoptopenjdk-15.jdk/Contents/Home
15.0.2
AdoptOpenJDK
x86_64
OpenJDK 64-Bit Server VM
15.0.2+7
OpenJDK Runtime Environment
15.0.2+7
```

The issue is that Gradle is probing the JVM to determine its version and isn't expecting the "Listening for transport dt_socket at address: 53880" line in the output.

The workaround is to edit `~/.attachme/conf.sh` to switch jdwp to 'quiet' mode:

```
JDWP_ARGS="${JDWP_ARGS:=transport=dt_socket,server=y,suspend=y,quiet=y,address=${JDWP_ADDR}:${JDWP_PORT}}"
```

Would be nice if the workaround was not needed.
