Remove databricks CI checks

[glsdown]

Overview

There are issues with running dbt-databricks via GHA, which means that the CI checks are continuously failing and we've been unable to get a release out. Therefore, this removes those checks (temporarily), and instead they will need to be run locally prior to any dbx changes.

Tests to run locally:

tox -e integration_databricks_1_3_0
tox -e integration_databricks_1_4_0
tox -e integration_databricks_1_5_0
