[rickstaa]

What does this pull request do? Explain your changes. (required)

This pull request ensures that the build.yaml action script also creates a release under a ai-video/latest path. This was done to simplify the binary installation in the docs.

[!WARNING] This logic may fail if additional tags are created on the ai-video branch. However, because this is a temporary solution and the ai-video branch follows a distinct versioning scheme separate from the main branch, investing in extra engineering was deemed unnecessary.
