[bitnami/elasticsearch] remove copyTlsCerts init container

[ianroberts]

Description of the change

Remove the initContainer that copies TLS certificates from the secret to the emptyDir volume and revert to mounting the secret directly into the various statefulset pods.

Benefits

Fixes #31872, renewed TLS certificates will be automatically reloaded by the various pods.

Possible drawbacks

The initContainer was initially introduced as a way to work around errors that occurred when running the Elasticsearch container as root (see #25280). This PR will revert to the previous behaviour that broke that use case, but I believe the right place to fix that problem is in the container image, not in the chart, and I have submitted bitnami/containers#77525 to that effect.

Checklist

• Chart version bumped in Chart.yaml according to semver. This is not necessary when the changes only affect README.md files.
• Variables are documented in the values.yaml and added to the README.md using readme-generator-for-helm
  • I have removed a number of variables from values.yaml and from the README, nothing has been added
• Title of the pull request follows this pattern [bitnami/<name_of_the_chart>] Descriptive title
• All commits signed off and in agreement of Developer Certificate of Origin (DCO)

It probably makes sense to fix bitnami/containers#77525 first, then update the image version in this PR's values.yaml before merging.

Not stale but still blocked waiting for bitnami/containers#77526 - I will rebase once this is merged and a fixed container image is released.

[ianroberts]

Rebased, but still needs @migruiz4 to approve the underlying containers fix before it makes sense to merge this one.
