Missing git dependency when installing SSS packages via git

Summary

When down-sizing the image, we removed a git dependency that we still need for installing server-sid scripting packages via pip install git+....

Expected Behavior

Package should install.

Actual Behavior

linkahead start terminates with

Waiting for server at localhost:10443 ......... reached

Steps to Reproduce the Problem

1. Add a package installed via git to your profile's scripting section, e.g.

   scripting:
     packages:
       caosdb-crawler:
         mode: "pip"
         package: "git+https://gitlab.indiscale.com/caosdb/src/caosdb-crawler.git@dev"

2. Start linkahead 0.15.0

Specifications

• Version: LinkAhead 0.15.0
• Platform: any

Possible fixes

Add git installation to image.

Workaround
