GUI: Small Updater refactor & Set correct permissions on Linux when extracting files (#4315)

* ava: Refactor Updater.cs

Fix typos
Remove unused usings
Rename variables to follow naming scheme

* ava: Set file permissions when extracting update files

* gtk: Apply the same refactor to Updater.cs

* updater: Replace assert with if statement

* updater: Remove await usings again
