feat: New update checker (#370)

* New App Updater, fixes #361

Telemetry/UpdateChecker only checks for new updates and sends a signal
with information weather update is available or not. Widgets and custom
dialogs now show chagelogs and direct download button depending upon OS.

It also provides some finer control over the update checker, so user can
see indeterminant progress of the update check and even cancel the
check. The Update UI has been made much cleaner and so has been the
code.

The changelog view supports full markdown formating, with the exeception
that mardown literals like `#` are also shown.

* Revert cmake version to 6.5.0

* Replaces tabs with spaces and add Qt5::Widgets link

* Fix(CI): Linux case sensitive include

* refactor: Improve the update checker and require Qt ^5.14

1. Use the Markdown of QTextEdit introduced in Qt 5.14 instead of the
   markdown_highlighter, hence require Qt ^5.14.
2. Many improvements. It's hard to list all of them, and it's better
   to read the codes.

* feat: show on top instead of raise

* feat(UpdateChecker): show more changelog when update is available

1. The update checker is refactored.
2. Now more changelog is shown. The changelog of a version is shown,
   iff the following are satisfied:
   - This version is valid (i.e. three integers separated by a dot).
   - This version is strictly higher than the current version.
   - One of:
     - This version is the first patch version of a minor version.
     - This version is of the same minor version as the latest release.

Perhaps some other changes are also introduced with the refactor.

 **First time to developing?** There's a big difference between developing and competitive programming, but it's not hard. The first thing you should know is Object-Oriented Programming. Basically, you need to know how classes work in C++, and you should know it's a rule to put the class definitions in the `.h`/`.hpp` files, and put the implementation of the functions in the `.cpp` files. The source code of the CP Editor is a good example. Google for what you want to implement is usually helpful. Copy and modify the source codes if you want to implement something similar to an existing feature. If you are looking for an IDE for developing, [VS Code](https://code.visualstudio.com/) is probably a good choice.
 
-**First time to Qt?** Don't be afraid, Qt is not hard to get started. You have to install Qt>=5.12 and CMake>=3.5 first. Linux users may install them using the package manager on your system.

Read the [build from source](doc/INSTALL.md#Build-from-source) section to learn how to build.

 **Впервые в разработке?** Существует большая разница между промышленным и спортивном программированием, но это не так уж и трудно. Первое, что Вы должны знать - это Объектно-Ориентированное Программирование (ООП). Вам нужно знать, как работают классы в C++, что нужно поместить определения классов в `.h`/`.hpp`, а поставить выполнение функции - в `.cpp` файлы. Хорошим примером может служить исходный код CP Editor. Искать в Google/Яндекс то, что Вы хотите реализовать, тоже полезно. Скопируйте и измените исходные коды, если Вы хотите реализовать что-то похожее на существующие функции. Если Вы ищете IDE для разработки, то [VS Code](https://code.visualstudio.com/) - достойный выбор.
