Fix docs: translate key missing quotes

[drmzio]

Just spent a good hour trying to figure out why the translate key wasn't outputting the translated text. The translate key must be in quotes when calling it inside the translate twig filter. 👍

site.name is a variable here, it should not be quoted. The next example shows a string key.

@mjauvin Are you sure about that? Just checked site and site.name and they're never declared as variables anywhere. The example provided in the docs reference the site.name key in the theme.yaml

translate:
    en:
        site.name: 'My Website'
        nav.home: 'Home'
        nav.video: 'Video'
        title.home: 'Welcome Home'
        title.video: 'Screencast Video'

The only way to pull the values is by calling {{ 'site.name'|_ }} in quotes.

If it is referring to that key in the theme translation, then you are correct. My appology.
