Skip WebUI prompt if --bridge passed, Detailed error messages if bridgeData.py fails to load (#1483)

# Description

Please include:
- [x] relevant motivation
- [x] a summary of the change
- [ ] which issue is fixed.
- [x] any additional dependencies that are required for this change.

Fixes a small typo of "Bridg" in horde_bridge.sh
Makes webui.sh skip asking for StreamLit/Gradio if --bridge is passed
More detailed error messages if bridgeData.py is missing/malformed
(previously it would only say no bridgeData found, which caused
confusion when bridgeData did exist but was incorrectly formatted)

# Checklist:

- [x] I have changed the base branch to `dev`
- [x] I have performed a self-review of my own code
- [x] I have commented my code in hard-to-understand areas
- [ ] I have made corresponding changes to the documentation
