Kafka dev service redpanda container failing with Text file busy
### Describe the bug

While using the Kafka Dev service I entered into a racing condition on the writing of the startup redpanda.sh script and its execution resulting in the following stacktrace:

sh: 1: /var/lib/redpanda/redpanda.sh: Text file busy
```

### Expected behavior

The dev services / redpanda container start correctly and the QuarkusTest depending on it executes correctly.

### Actual behavior

In a racing condition the following startup line:

```sh
sh -c "while [ ! -f /var/lib/redpanda/redpanda.sh ]; do sleep 0.1; done; /var/lib/redpanda/redpanda.sh
```

fails with:

```
sh: 1: /var/lib/redpanda/redpanda.sh: Text file busy
```

In DevservicesKafkaProcessor we can see that a methods transfers this shell script contents after the docker container has been started, probably to inject configuration from Java.

I think the pb is that in my case is that the contents are still being written on disk while the condition of existence already becomes true and the startup comand gets executed. Indeed the Test file busy error is raised when executing an executable file that is being edited.

### How to Reproduce?

As said it is not systematic... Happens only rarely.

### Output of `uname -a` or `ver`

### Output of `java -version`
