0.0.5

Fixes and additions:

• Added the without_erase_previous_file method to GithubUpdater.
• Modified the update behavior: Regardless of the erase_previous_file setting, the new file is now downloaded as new_{app_name} if an existing file is present. If no existing file is found, it is downloaded directly as {app_name}. This change prevents unnecessary movement of the original file in case the downloaded file is corrupted.
• Switched from native-tls to rustls-tls for reqwest.
