ci: push charts to GHCR

[onedr0p]

Important

After this is merged and charts are released you might need to make the packages public from here

I also bumped some deps as well.

Fixes: #550

I'm going to delegate to @stevehipwell for his expertise here plus I know he has some much improved CI he wants to push :)

[onedr0p]

@patrick-stephens Ah, yes. I did just discover his comment here. However I think merging this is a good stop-gap until more work can be put into getting his action working here, or unless @stevehipwell wants to supersede this PR with his own using his action in the meantime.

[stevehipwell]

@onedr0p thanks for the PR. I'm planning on adding my PR soon, but this may be a good stopgap.

@patrick-stephens could you check if the OCI packages are public? Once they are I'll manually upload a chart version that we can test before making a decision on merging this change.

[patrick-stephens]

No packages exist yet so they are not public, assuming we are pushing to ghcr.io/${{ github.repository }} which would map to ghcr.io/fluent/helm-charts.

We can change the package visibility easily enough, I'm not sure what it will default to initially and we may need to link it to this repo potentially - sometimes the action does that for you automatically.

Bit surprised we have to update the actions, I'm guessing we should have a dependency PR for that somewhere.

It looks like Dependabot has been ignored so it's stopped checking, I've just manually re-triggered it.

[stevehipwell]

The changes don't look right here, has there been a merge issue?

[onedr0p]

@stevehipwell what do you mean, it looks normal to me?
