This should fix#435 for Helmfile v0.x releases since the next v0.150.0.
We introduce a new envvar to opt-in to the new YAML library, so that you can give it a shot before upgrading your Helmfile to v1. The same envvar can be used to opt-out of the new YAML library after you upgrade to Helmfile v1, giving you a more flexible migration story.

This is a successor to #596. We need a smooth migration path from `gopkg.in/yaml.v2`, and this pull request moves it forward with `goccy/go-yaml` instead of `gopkg.in/yaml.v3`. Merging this unblocks users stuck in Helmfile v0.146.x or earlier due to #435, so that they can upgrade to 0.147.x or greater without updating their helmfile configs.
We previously tried to upgrade to `yaml.v3` (https://github.com/helmfile/helmfile/issues/394) in Helmfile v0.x, presuming it won't break anything. Apparently, it broke use-cases where you want to layer release's `values` field over three or more release templates and releases (#435).
We then tried to bring back `yaml.v2` for Helmfile v0.x and keep `yaml.v3` for the upcoming Helmfile v1. However, it failed due to incompatibility in the Unmarshaller interface between `yaml.v2` and `yaml.v3` (https://github.com/helmfile/helmfile/pull/596).
`goccy/go-yaml` is, from my observation, a well-maintained alternative to `yaml.v2`. One of its premises is that it enables us to swap the implementation from `gopkg.in/yaml.v2` to `goccy/go-yaml` just by replacing the import directive. It seems to use the same `Unmarshaller` interface as yaml.v2 too.
Once this PR gets merged, I'd like to follow-up with adding a new build-time variable and an envvar to set the proper default for the yaml parser Helmfile uses and the ability to switch the parser at runtime. All in all, the next Helmfile release, v0.150.0 will get reverted to use `gopkg.in/yaml.v2` by default which resolves#435.
New users who started using Helmfile since any of v0.148.0, v0.148.1, and v0.149.0 might be already relying on the new behavior, They might need to specify a new envvar to enable `goccy/go-yaml`.

All the dependencies get correctly installed when dealing with remote
charts.
If there's a local chart that depends on remote dependencies then those
don't get automatically installed. See #526. They end up with this
error:
```
Error: no cached repository for helm-manager-b6cf96b91af4f01317d185adfbe32610179e5246214be9646a52cb0b86032272 found. (try 'helm repo update'): open /root/.cache/helm/repository/helm-manager-b6cf96b91af4f01317d185adfbe32610179e5246214be9646a52cb0b86032272-index.yaml: no such file or directory
```
One workaround for that would be to add the repositories from the local
charts. Something like this:
```
cd local-chart/ && helm dependency list $dir 2> /dev/null | tail +2 | head -n -1 | awk '{ print "helm repo add " $1 " " $3 }' | while read cmd; do $cmd; done
```
This however is not trivial to parse and implement.
An easier fix which I did here is just to not allow doing
`--skip-refresh` for local repositories.
Fixes#526
