[nginx-static]: Fix nginx-config mount issue

[Sturgelose]

Thought: why not extending this helm chart? https://artifacthub.io/packages/helm/bitnami/nginx

Even there are configs to handle what it trying to be handled in this chart (here)

I feel we are just rewriting this one but.... with git and disk support, which:

• git could be replaced by Flux
• disk usage in a static site, I don't really see the point (or use-case) why we might need it...
• security contexts shouldn't be needed for a static nginx server...

I don't want to suggest recreating the chart from scratch, but, I feel we are maintaining this (of course with low cost), when we could use the community :sweat_smile:

Anyways, approving as for the time being this is useful.

Valid concern... This chart was written based on legacy workflows where we would create unique Helm Charts to achieve the same result. Unsustainable. Crazy idea: let's make a single generic one, and so this Chart was born. We can check in the future what to do, but this is yet another open source alternative to use. 🙂
