Enhance interface parsing in 'show vrf all detail' parser

- Implemented a general regex pattern to capture all interface names
    - Replaced the previous regex that relied on specific interface prefixes (e.g., Gi, Bun, Ten, etc.) with a more general pattern `r'^(?P<intf>[A-Za-z][-A-Za-z0-9/.:]+)$'`
- Introduced `in_interfaces_section` flag for accurate section tracking
