"View in Looker" button for Explore does not pick the external_base_url from config

[k7ragav]

Describe the bug
For Explores in Lookers, when you click on the 'View in Looker", it leads to the URL that is used in base_url. However, even when you set the external_base_url setting in config, it does not get overwritten like how it does for Looker Chart and Dashboards.

To Reproduce
Steps to reproduce the behavior:

1. Import Looker content either through CLI or UI and set the external_base_url to a different URL from base_url
2. Click on 'View in Looker' link
3. It will open with the base_url and does not use the external_base_url

Expected behavior
When clicked on View in Looker and if the external_base_url is set, that external_base_url needs to be part of URL leading to Looker instead of the base_url
