Rename Dast profiles and Pre-scan sidebar occurrences to a drawer

This MR is a follow-up of this comment

In order to be consistent with gl-drawer component name following component should be renamed from sidebar to a drawer:

1. All files in folder ee/app/assets/javascripts/security_configuration/dast_profiles/dast_profiles_sidebar
2. pre_scan_verification_sidebar.vue
3. pre_scan_verification_sidebar_spec.js
4. All files in folder ee/spec/frontend/security_configuration/dast_profiles/dast_profiles_sidebar

Sidebar -> Drawer sidebar -> drawer
