Fix: Update README, license consistency, and Helm chart configurations

This commit addresses several issues to improve repository accuracy and CI reliability:

1.  **README.md Updates:**
    *   I corrected the Helm repository URL to `https://malarinv.github.io/iperf3-monitor/`.
    *   I updated the default exporter image name to `ghcr.io/malarinv/iperf3-monitor` in examples.
    *   I revised the License section to accurately reflect the AGPLv3 license present in the `LICENSE` file, removing contradictory statements.

2.  **License Consistency:**
    *   I confirmed `LICENSE` file contains AGPLv3. README now correctly refers to it.

3.  **Helm Chart Adjustments:**
    *   `charts/iperf3-monitor/Chart.yaml`: I removed placeholder comments for clarity. Versioning is handled by the release workflow.
    *   `charts/iperf3-monitor/values.yaml`: I updated `exporter.image.repository` to `ghcr.io/malarinv/iperf3-monitor` to match the CI build image name.

4.  **CI Workflow Verification:**
    *   I verified that `.github/workflows/release.yml` correctly uses `yq` to set chart versions from Git tags and publishes to the correct GitHub Pages URL. This should prevent the previously noted `chart.metadata.version is required` error, which was associated with an older version of the release workflow.

These changes ensure that the documentation is up-to-date, the Helm chart defaults are correct, and the CI pipeline for chart publishing is robust.
