Encourage Acoustic Workbench Users to Cite Open Ecoacoustics DOI

[nellihol]

We should start asking users to cite our project DOI in their work. This addition would help us more effectively track our platform use and academic impact.

• - Add a citation example on the platform, encouraging users to cite our project DOI (https://doi.org/10.47486/PL050).
• - Include the DOI URL in the README file and other relevant documentation sections.
