Update Keycloak chart dependencies and metadata

Updated the `Chart.yaml` file for the Keycloak Helm chart. The
dependencies section was modified to use a more structured format
for listing dependencies. The condition for the PostgreSQL chart
was updated to improve clarity. Additionally, the chart version
was bumped from `24.9.1` to `24.9.2`, reflecting the latest
changes and improvements in the chart.

The description was reformatted to enhance readability and provide
clarity on what Keycloak offers. Minor adjustments were also made
to the keywords and maintainers sections for consistency and
accuracy. No breaking changes or impacts on existing deployments
are expected from this update.
