Git folder is large

### Describe the bug
The repo is growing rapidly(!) Caused by every version of the 50mb asset zip file is beeing kept in the git history.

Could this zip file instead be generated on-demand from inside the deploy.ps1 script?
Should the repo be cleaned up with `git filter-branch` or something similar to remove the large .pack file and lower the repo size?
