remove optional flag from --dbt dependencies

Resolves #526
Resolves #525

Makes the following packages non-optional:

dbt-artifacts-parser = {version="^0.2.5"}
dbt-core = {version="^1.0.0"}

The intent is to simplify installation for --dbt users.

We can tell folks to pip install data-diff, and they will be prompted with a single instruction for their database provider vs. the current two. Something like:

This will increase the number of required dependencies

[dlawin]

this would essentially revert #412

BQ & Databricks?

BQ & Databricks?

We could add those as well, the only reason I excluded is that they are not listed as dependencies at all currently (not even as optional ones)

Got it--I just want to make sure users of BQ and Databricks are able to get started with the same ease as the other DBs you listed, and they don't have to run these commands (which are currently listed in the documentation):

• pip install data-diff 'data-diff[dbt]' google-cloud-bigquery
• pip install data-diff 'data-diff[databricks,dbt]' -U
