ci: rename build-and-check stage to test

The SAST CI template was recently updated and now includes a few additional jobs. Since GitLab UI's CI configuration does not override those new jobs, the YAML file is considered invalid: https://gitlab.com/gitlab-org/gitlab-ui/pipelines/83190158

Found errors in your .gitlab-ci.yml:
bandit-sast job: stage parameter should be pre-build
build-and-check
deploy
publish

To fix this, we either need to:

1. override all the jobs that were added OR
2. have a test stage in our CI setup

The present MR goes for option 2 by renaming the build-and-check stage to test.

Additionally the following jobs have been removed from the YAML since we don't need to override them anymore as they will be run in the test stage by default:

• sast
• dependency_scanning
• license_management
