fix: Replace Desktop util with built-in BrowserUtil (fixes #6020)

[exigow]

Description

I had the exact same issue as in #6020 when setting up the extension locally. Every attempt to log in ended in a freeze (100% reproducible).

My change removes the Desktop class and replaces it with a built-in OS-agnostic BrowserUtil. Removing this class also removes the use of the SLF4J logger, which was the cause of the mentioned exceptions.

Wow, didn't realize we had a hand-rolled browser util implementation when there is a built-in from IntelliJ. This was likely a very old artifact from one of the original OS contributors that helped us set up the original JetBrains plugin.

Great find!
