Feature Request: Add installation option via Helm

[sujaya-sys]

Status Quo

Today, the only option to install the operator is manually via manifests (install.yaml). See https://github.com/checkly/checkly-operator/blob/main/docs/README.md#installation for context.

Request

Add support for installation via Helm chart.

A lot of teams work with Helm, making this a more convenient way to install the operator and tweak the default configuration provided in the install.yaml file.

Dropping in some notes from a feedback call:

• Publish operator helm chart to public artifact repositories to make it easily accessible (each cloud provider has artifact registries we could utilize here)
• Ideally, changes are auto-released i.e. auto-publish the helm chart as an artifact
• Something for the future: You can annotate all values within the helm values file and it'll automatically built the documentation for it
