Add ability to update project configuration

### What problem are you trying to solve?

Currently, there is no way to update project configuration (like build step or entrypoint) without unlink, and linking again the same github repo.

### Describe the solution you'd like

There should be possible to update just the project configuration (which will trigger automatic deployment) without ulinking/linking the github repo.

### Describe alternatives you've considered

I understand this can be changed with github actions, but I feel, if you can set this configuration when linking github repo, you should also be able to update it.
