Plan out deprecation for kedro test and kedro lint

[merelcht]

Description

As part of the research in #1293 it was found that several CLI commands aren't used that much. kedro lint and kedro test were among these commands, but since these commands add to Kedro's value proposition of adding best software engineering practices to ML projects, we need to investigate more what approach we should take if we deprecate those commands.

Context

We have end to end test (test.feature) in place that run kedro test and kedro lint on a new Kedro project to ensure the Kedro project template can be linted and tested correctly. Even if we deprecate those commands we want to ensure that the project template adheres to best practices when it comes to linting and testing (e.g. being able to run pytest).

As part of this task:

• Should kedro test and kedro lint be deprecated? #1766
• Should testing and linting dependencies and configuration be dropped from starters and / or templates? #1849
