Add devcontainer Configuration for easy integration & reproducibility

[DZiso]

-Lokal VSCode(LatexWorkshop) configuration for correct commands -Docker image with all dependencys nicely bundled -Devcontainer definition with plugin installation -Updated Thesis.pdf for comparison

Whats missing: -documentation

[DZiso]

This is a integration of the template into VSCode as a Devcontainer with automatic Plugin installation & configuration via Workspace.

To use: Install VSCode with remote Container Extension (https://code.visualstudio.com/docs/remote/containers) Open Remote Container Folder -> Select git Repository To Compile execute VSCode command(strg + p) "Latex Workshop:Build Latex Project" on Thesis.tex

Is there interest in this or is everyone fine using a local installation ?
