fix(eventsub): compilation issues

[Nerixyz]

Compiling the library as an object library causes some object files to not be linked to the final executable if it depends on the library transitively. Compiling the library as a static library (like other libraries) solves this. I don't know why the default is an object library.

Remaining issues:

• chatterino2/src/providers/twitch/EventSub.cpp

  Lines 269 to 271 in 38560ba

  	auto [host, port, path] = getEventSubHost();
  	this->mainThread = std::make_unique<std::thread>([=] {

  Requires at least Clang 16 (see https://stackoverflow.com/q/46114214/16300717).
• At least Boost 1.83 is required for boost::json::try_value_to( value const&, Context const&) (Ubuntu uses 1.81)
• For GCC 9, fix: remove unused include twitch-eventsub-ws#3 is required

At least Boost 1.83 is required for boost::json::try_value_to( value const&, Context const&) (Ubuntu uses 1.81)

Once Chatterino/docker@ea62e3c CI is done, Ubuntu builds will use Boost 1.84

The docker image doesn't appear to be pushed.
