Remove Duplicate Dataset Name Column from Data Map

[SteveDMurphy]

Bug Description

The data map currently contains two columns for the data map name (once for the fides dataset name near the front and again for the actual data map). This currently feels unnecessary

Steps to Reproduce

1. fidesctl apply demo_resources/
2. fidesctl export datamap
3. See the duplicate dataset name in columns A and U

Expected behavior

Either get rid of one of the columns of data, or conversely, look at being more specific with the source of the personal data (collection possibly?)

Environment

• Version: 1.6.1
• OS: Darwin
• Python Version: 3.9
• Docker Version: 20.10.14

Additional context

This was known earlier but highlighted when updating the columns to be programmatically named with a duplicate key error from Pylint in #779

@mfbrown this stems from the original datamap template that was prescribed for us, but seems to make sense to review as part of the UI changes and would love your thoughts/input - thanks!
