chore: enhance VHS GIF generation workflow

## Summary

Updated the GitHub Actions workflow for generating VHS demo GIFs. Introduced a dedicated step for setting up Go and streamlined the GIF generation process by executing multiple VHS commands in sequence.

## Changes

- Added a step to set up Go version 1.25.1.
- Replaced multiple `charmbracelet/vhs-action` usages with a single run command to generate GIFs from all tape files.
- Ensured the GIF generation step is skipped for dependabot commits.
