Quickfix: Pin Gradio <6.0 to fix GUI Audio TypeErrors (#862)

Problem: Gradio >=6.0 crashes GUI:
TypeError: Audio.init() got unexpected keyword 'show_download_button'/'buttons'

See:

BirdNET-Analyzer/birdnet_analyzer/gui/single_file.py

Line 127 in a5a9e1d

segment_audio = gr.Audio(autoplay=True, type="numpy", show_download_button=True, show_label=False, editable=False, visible=False)

Fix: Update pyproject.toml:

gui = [
  ...
- "gradio>=5.46",
+ "gradio>=5.46, <6.0",
  ...
]

Test: pip install -e '.[gui]' → GUI starts without errors.

Future: Gradio 6 migration needed.

Fixes #862

Pull request overview

This PR is a quickfix that pins the Gradio dependency to versions below 6.0 to prevent GUI crashes caused by breaking API changes in Gradio 6.0. The issue #862 reported that Gradio 6.0 removed the show_download_button parameter from the Audio component, causing TypeError exceptions when launching the BirdNET-Analyzer GUI.

Changes:

• Add upper bound constraint to Gradio dependency (< 6.0) while maintaining minimum version requirement (>= 5.46)
