Network Drive connector is not retrieving last modified date

[m-amano]

Problem Description

The Network Drive connector's format_document method could potentially include the file's last modified date. Currently:

1. _timestamp field uses change_time, which only updates when file permissions or metadata changes
2. The actual last modified date of the file content (last_write_time) is not captured

Questions:

• Is using change_time for _timestamp the intended behavior?
• Would adding last_write_time as a new field be valuable for tracking actual file modifications?

Proposed Solution

Add last_write_time to capture when file content was last modified:
