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.

The Arduino company is no longer soliciting monetary donations. Community members who wish to contribute to the project
still have opportunities to do so via the other options listed here.

* Add a copy output button to serial monitor

If the arduino collects some data that you want to store on your
computer, a rather simple way is to write it to the serial monitor and
copy it to the clipboard. This commit introduces a button that copies
the whole content of the serial monitor to the clipboard to make this
rather simple. It is a new component added to the menu, and does not
change the behaviour of other compontents.

* Test merging lines to str in serial monitor utils

Adds a test for merging one or more lines to a single string. It is
supposed to just concatenate the content of the lines, without doing
anything else. This method is used when copying the serial monitor content to
the clipboard.

* Add copy output translation key

This serves as an addition to the previous commits. It is the result of
running `yarn i18n:generate` on the state after adding the copy output
button to the serial monitor (see 2df3f46). I hope that this will
resolve the current Github action failure.

* Improve readability for serial monitor utils

Replace return statement in inline method by direct statement, some
minor formatting changes. Does not affect the functionality.

* Rename linesToMergedStr in monitor-utils

Renames the method linesToMergedStr to joinLines in the serial monitor
utils. This brings the name more in line with truncateLines. No
functionality changes.

* Move label and icon registration for copy serial

Moves the registration of the label and icon for the copy output
button of the serial monitor to the toolbar item registration. Before,
it happened at the command registration, but is not necessary at this
level, as the icon and label are meant for the toolbar button only.

* Do not update widget when copying output

No longer updates the serial monitor output after its content is copied.
Copying the content does not change anything for the view, so there is
no need to update.

Prefix links with "/docs/" so they work in the Contributing tab

Clarified the limitations of the Arduino IDE localization framework and added information about future language support.
