feat: Use bundled chart 

BREAKING CHANGE: This is not technically a breaking change as AutoDeploy
pipelines still use the v0 chart, however, we decided to increment a major
version for the safety.

### v1.0.0



Before v1.0.0, auto-deploy-image was downloading a chart from [the chart repository](https://charts.gitlab.io/),

which was then uploaded by the [auto-deploy-app](https://gitlab.com/gitlab-org/charts/auto-deploy-app) project.



Since auto-deploy-image v1.0.0, the auto-deploy-app chart is bundled into the auto-deploy-image docker image as a local asset,

and it no longer downloads the chart from the repository.
