Add application security testing to the navbar
This adds the tools listed in https://docs.gitlab.com/ee/user/application_security/#security-scanning-tools in the navbar.
I opted to not list all of them alphabetically:
- Container scanning is first for alphabetical reasons.
- Dependency Scanning and Dependency List are second and third for alphabetical reasons.
- SAST is before DAST as it's probable to be used more, since you need a deployed applications for DAST.
- Security dashboard is second to last since for it to function it needs one or more of the above.
- License compliance is last since it's kinda irrelevant with security.
