Adding converters produces an invalid configuration.yaml

[frank-f]

If I add an external converter, the resulting configuration.yaml looks like this:

external_converters:[file.js]

Note the missing whitespace between key and value. That's invalid and zigbee2mqtt won't start like that.

You have to put them in a directory, not in the configuration.yaml (this changed in z2m 2.0), docs: https://www.zigbee2mqtt.io/advanced/more/external_converters.html#external-converters
