…rough `open-file` event (#2693)

* fix: wait for `initialWindow` to be set before opening sketch from file

The system used for localization of this project leverages the infrastructure and data that already exists for VS Code.
These assets are applicable to Arduino IDE 2.x due to the project being built on the Eclipse Theia IDE framework. In
this way, the Arduino IDE developers and community are only responsible for internationalization and localization of the
Arduino-specific strings (e.g., "Sketchbook") used in the IDE's UI.

The unfortunate downside to this approach is that there is a hard technical limit on localization of the project to
languages for which a VS Code "language pack" is available.

It will be helpful to clearly communicate the set of languages for which we are able to ship contributions from
translators.

Likewise, it will be useful to also communicate that, we are able to ship contributions of translations of Arduino CLI
user interface strings for any language. This is due to the fact that the Arduino CLI codebase uses a completely
different internationalization system that does not impose any technical limits on the scope of localization.
