chore(chart): bump proxysql-operator chart 0.4.0 -> 0.5.0

[jesmarcannao]

Bumps the operator Helm chart to 0.5.0 to match the released v0.5.0 operator image (the ProxySQLConfig-union fix, #84).

• version + appVersion → 0.5.0. With values.yaml image.tag: "" falling back to appVersion, the chart's default image is ghcr.io/proxysql/proxysql-operator:0.5.0.
• CRDs unchanged — the union fix added no CRD fields (v0.4.0's TLS additions were already present). helm lint clean.

Release note: chart-releaser runs on v* tags (via release.yaml, skip_existing: true). The v0.5.0 tag predates this bump, so it published the image but skipped the chart (still 0.4.0). To actually publish proxysql-operator-0.5.0 to the helm repo, either re-point v0.5.0 to include this commit or let the next release pick it up — maintainer's call.
