feat: Add basic email parsing and Gmail domain detection in EmailValidate class

- Prompted user for an email address via Scanner.
- Parsed the email string to:
  - Extract the username (substring before '@')
  - Extract the domain name (substring after '@')
- Printed both username and domain.
- Checked if domain starts with "Gmail" (case-sensitive).
- Extracted the domain prefix (substring before first '.') and validated if it's "gmail" (case-insensitive).
- Closed Scanner to prevent memory/resource leaks.

Note:
- This version assumes valid email format and does not perform safety checks for missing '@' or '.'.
- Can be improved by adding validation before substring operations to prevent runtime exceptions.
