Summary of Changes

Hello @mag123c, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request focuses on enhancing user privacy by removing Personally Identifiable Information (PII), specifically the user's email address, from the /about command's output. This change ensures that sensitive user data is not inadvertently exposed when command output is shared, improving the overall security and privacy posture of the application.

Highlights

• Privacy Enhancement: Removed the user's email address (Personally Identifiable Information - PII) from the output of the /about command to prevent its unintentional exposure, especially when users share this output in bug reports.
• Code Refactoring: Eliminated the usage of UserAccountManager in aboutCommand.ts as it was no longer needed to retrieve user email.
• UI Update: Modified the AboutBox component to no longer display the user's email, ensuring only 'Logged in with Google' is shown for OAuth users.
• Type Definition Change: Updated the HistoryItemAbout type to remove the userEmail field, reflecting the removal of email data from the /about command's data structure.
• Test Updates: Adjusted relevant test files (aboutCommand.test.ts, AboutBox.test.tsx) to align with the removal of user email handling and display.
