Feature request - enable icon on non-r based chunks.

[alexiswl]

Enable klippy for code chunks that are not r.

Even when I'm not using R, I'd like to be able to use this tool for documentation.

Currently the following segment would not place a 'copy to clipboard' label as required

# Create the logs directory

```{bash create_logs, echo=TRUE, eval=FALSE}
mkdir -p logs
```
