Update getting started to use find_package()

[danimtb]

Coming from #1513 (comment) cc/ @Minimonium

We should consider the update of the getting started to the cmake_find_package generator as it seems to have less friction.

With this, we should adjust the examples CI to run the jobs every day to verify that all the examples in the documentation can run in all platforms without issues. This will prevent that any change in the CMake target names introduced in conan-center-index breaks the examples (especially the getting started one).

Should it be the cmake_find_package(Modules) or the cmake_find_package_multi(Configs)?
