Subject: [PATCH] Fix #21406: Hide repo information from file view/blame mode
 (#21420)

# Summary

The repo information such as description, stats and topics are getting
displayed in the top-bar when viewing a file. This has been fixed to
display the repo information only while navigating the repo and not
while viewing or blaming a file from the repo

## Before fix

Screenshot from the issue

## After the fix

- **Repo homepage**

The repo description, topics and summary will be displayed

- **When opening a file**

The repo description, topic and summary has been conditionally hidden
from the view

- **When running blame on a file**

> This was originally not part of the issue #21406. However the fix
seems relevant for the blame view as well.

- **From within a directory**

The repo description, topics and summary will not be displayed

Supporting integration tests have also been added.
