Activate before *any* language

VS Code fires `onLanguage` activation events before `*`,
which can lead to language-based extensions being activated
before this one.
This change adds the generic `onLanguage` activation event
*without a language identifier*,
which [according to the documentation][1]
should activate this extension before any language used.

Closes #109
