ELE-444 Not require `git` for `edr` docker image to work.

Is your feature request related to a problem? Please describe.
Currently, upon edr's initialization, we run dbt debug.
We do this mostly to ensure that the elementary profile is available and set up correctly.
dbt supports reading the profiles.yml from either the working directory or ~/.dbt/profiles.yml,
so this is a way of handing the responsibility to them rather than re-implement the following logic.

The main problem is that dbt debug requires git to be installed and otherwise it fails which raises an exception at edr.
And in practice, not everyone has git installed.

Describe the solution you'd like

1. Either remove the call for dbt debug and search for profiles.yml and add a validation that it's set up correctly.
2. Keep it and only log it.
3. Other options.
