feat: add HELMFILE_INTERACTIVE env var to enable interactive mode (#1787) 

* feat: add HELMFILE_INTERACTIVE env var to enable interactive mode

This commit adds the `HELMFILE_INTERACTIVE` environment variable
to enable the interactive mode by default.
Anything other than `true` will disable the interactive mode.
The precedence has the `--interactive` flag.

* `HELMFILE_GOCCY_GOYAML` - use *goccy/go-yaml* instead of *gopkg.in/yaml.v2*. It's `false` by default in Helmfile v0.x and `true` by default for Helmfile v1.x.
* `HELMFILE_CACHE_HOME` - specify directory to store cached files for remote operations
* `HELMFILE_FILE_PATH` - specify the path to the helmfile.yaml file
* `HELMFILE_INTERACTIVE` - enable interactive mode, expecting `true` lower case. The same as `--interactive` CLI flag
