In older versions of Compass, we used `keytar` package to store credentials securely in the keychain. However, this package has been deprecated and is no longer maintained. In. COMPASS-6856, we switched to using `electron`'s built-in `safe-storage` module for secure credential storage.

In order to support users migrating from older versions of Compass (using keytar), to the one using `safe-storage`, we implemented a migration script that handles moving credentials from keytar to safe-storage.

The purpose of this ticket is to remove all the `keytar` related code and the migration script once enough users have migrated to the new version of Compass.
