v3.7.0

=====================================================================

--- New Features -------------------------

- Github Actions integration from 3.7.0 and up!

```yaml
  # try it out in gh actions
  - uses: wrynegade/scwrypts@main
    with:
      version: v3.7.0
      scwrypt: --name hello-world --group scwrypts --type py
      args: --message "hello from github actions ci <3"
```

--- New Scripts --------------------------

zsh/helm )
  smart helm template functions (simply pass a filename)
   - get-template
   - update-dependencies

--- Changes ------------------------------

- CHECK_ENVIRONMENT now uses proper argument parsing

- scwrypts/plugins loaded by setting in config or environment:
   SCWRYPTS_PLUGIN_ENABLED__plugin=1

- SCWRYPTS__GET_PATH_TO_RELATIVE_ARGUMENT was missed in the v2->v3
  refactor and has now been reincluded as SCWRYPTS__GET_REALPATH

+# Kubernetes `kubectl` Helper Plugin
+
+Leverages a local `redis` application to quickly and easily set an alias `k` for `kubectl --context <some-context> --namespace <some-namespace>`.
+Much like scwrypts environments, `k` aliases are *only* shared amongst session with the same `SCWRYPTS_ENV` to prevent accidental cross-contamination.
+
+
+## Getting Started
+
+Enable the plugin in `~/.config/scwrypts/config.zsh` by adding `SCWRYPTS_PLUGIN_ENABLED__KUBECTL=1`.
+Use `k` as your new `kubectl` and checkout `k --help` and `k meta --help`.
