feat: allow to specify dockerfile name in image_build_spec (#2223)

## Description:

Allow to specify the Dockerfile name in `ImageBuildSpec`.
Resolves #2187 

- Add a new `build_file` attribute in `ImageBuildSpec`.
- Update `ImageBuildSpec` tests and add custom build file tests
- Update the `ImageBuildSpec`, `TargetStageAttr` validator to `nil`
since it's an optional value.
- Update `ImageBuildSpec`docs.
- (not related) `go mod tidy`.
