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.

Previously a values template rendering failure resulted in a cryptic error message like:
```
g release templates in "input.yaml": failed executing templates in release "input.yaml"."foo1": failed executing template expressions in release "foo1".values[0] = "[98 97 115 101 76 97 98 101 108 58 32 34 123 123 32 103 101 116 32 46 82 101 108 101 97 115 101 46 76 97 98 101 108 115 32 92 34 98 97 115 101 92 34 32 92 34 78 79 84 95 73 78 72 69 82 73 84 69 68 92 34 32 125 125 34 10]": template: stringTemplate:1: unexpected "\\" in operand
```
The issue was that the values template at the value position of the YAML dict was printed as a formatted byte array. We now print it as a standard string so that it is easily readable.

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`.
