Install Gitaly dependencies for project archiving

What does this MR do?

Install Gitaly dependencies for project archiving 

Install tar, gzip and bzip2 into final Gitaly image.
Fixes empty bzip archives when a project is exported.

Changelog: fixed

• Issue occurred in: https://gitlab.com/gitlab-org/charts/gitlab/-/jobs/5554264567
• Original cause: Use GitLab base image as Gitaly base (!1584 - merged)
• Related Gitaly code: https://gitlab.com/gitlab-org/gitaly/-/blob/e66f6ec5ad5b47cb43e69a4690c3e9e1a9a49b4e/internal/gitaly/service/repository/archive.go#L105

Note: tar and gzip are already installed, but I think we should explicitly add them to the list to make sure they are installed even if the base image changes.
