Modernise top-level `README.md`

[moritzsommer]

Current Situation

Compared to the other repositories of the Eclipse Basyx project, our top-level README.md looks empty and not as visually appealing. Alternative examples can be found in:

• The GO SDK
  • Very clear structure, good overview
• The AAS Web UI
  • Summarising status badges
  • However, the emojis should not be adopted, as they appear unprofessional and AI-generated when used excessively

Furthermore, we currently link to the PyPI, but not the Conda release.

These are the implemented AAS specifications of the [current SDK release](https://github.com/eclipse-basyx/basyx-python-sdk/releases/latest), which can be also found on [PyPI](https://pypi.org/project/basyx-python-sdk/):

Proposed Change

The top-level README.md should be revised. Personally, I like the GO SDK's approach; we could ask them if we are allowed to adapt or improve it. Possible adaptations could include:

• More, better structured subsections
  • Introductory section
  • Table of Contents
  • Project Overview
  • Architecture Overview
  • Setup & Installation
  • ... (GO SDK)
  • Further Reading
• The BaSyx Python SDK logo in the introductory section
• Badges summarising the status of the repository
• Admonitions for highlighting
• A short introductory video, similar to the old Java SDK
• An FAQ
• An additional link to the Conda release
• ...

I know that more in-depth information is provided in the subrepository-specific READMEs, but we should still add a few more examples to the top-level README, as this is the first (and maybe last) piece of documentation that most users will see.
