How do you translate the main string?

It seems that ```Reading time: ``` is hardcoded into the plugin and isn't being translated. Which is understandable since it's not in ```languages.yaml```, but I don't see it being injected from any of the files in the plugin.

And yet, the ```{{ page.content|readingtime}}``` variable seems to include it. The minutes and seconds parts translates correctly, as expected because there are translations for it, but not the ```Reading time: ``` part. E.g. ```Reading time: 1 minuto```.

Is this an oversight that nobody has ever noticed/cared about or am I missing something obvious?

Start with languages.yaml and trace the implementation behind the {{ page.content|readingtime }} variable to find where the “Reading time:” label is assembled. Compare it with the existing minute and second translations; done means the label is translated consistently with the rest of the output.
