refactor(Application Search): Improve Linux compatibility

[ke1v]

Changes:

• Refactored LinuxAppIconExtractor to use sharp instead of calling convert on the command line as some Linux distros (notably Linux Mint) does not come with the convert package installed by default.
• Refactored LaunchDesktopFile to use gio launch as it appears to be installed on all Linux distros I tested (even KDE based ones)

@oliverschwendener I import sharp directly in LinuxAppIconExtractor. Let me know if you'd like me to create a module to handle image conversion. I'm also unfamiliar with electron-builder so I'm not sure if asar is the best way to handle packaging sharp (it wouldn't bundle without it)

[oliverschwendener]

Can you try packaging the app and check if it works with the newly added package?

rm -rf node_modules

pnpm config set shamefully-hoist true --location=project
pnpm config set auto-install-peers true --location=project
pnpm config set strict-peer-dependencies true --location=project

pnpm install
pnpm build
pnpm package

Tried it and it still doesn't package correctly without asarUnpack, which I think is because sharp uses C binaries. I could try switching to a pure Javascript image library if you don't want to use libraries with binary dependencies.

So, if this doesn't work when packaged I don't think we can merge it 🤷

[oliverschwendener]

If you want, you can open a separate PR for the refactoring in LaunchDesktopFile so we can merge that.

Sorry about the late reply, but I think I may have misworded my initial issue. sharp works and packages without issue with the addition of asarUnpack but I thought you had disabled asar for electron. However I believe it is enabled by default so this shouldn't be an issue.

Generally I am very conservative when it comes to adding more dependencies, especially when they're only used on one platform. But let's give this a try as it simplifies the code a lot regarding the icon generation on Linux. Nevertheless, I reserve the right to remove this package anytime if it proves to be a burden.
