Add support for resolving '~' in ageKeyFile and gcpCredentialsPath

Enhance the getSopsGeneralOptions function to properly handle file paths starting with '~' in both ageKeyFile and gcpCredentialsPath. This update allows these paths to be resolved to the user's home directory, improving usability and flexibility in path specification within sopsrc.
