ci: simplify semantic release (#76)

This pull request updates the deployment pipeline and Helm configuration
to streamline image tagging and simplify Helm chart updates. The main
change is that all Docker images are now tagged with both the version
and `latest`, and the Helm chart is updated to use the `latest` tag for
all services. Additionally, the workflow steps that previously automated
Helm value updates and commits have been removed, reflecting a shift to
a simpler release process.

**Image Tagging and Helm Chart Updates:**

* Updated all Docker build commands in the `Makefile` to tag images with
both the specific version and `latest`, ensuring the most recent build
is always available under the `latest` tag.
* Changed the Helm values in `infrastructure/rag/values.yaml` for all
services (`mcp-server`, `rag-backend`, `frontend`, `admin-backend`,
`document-extractor`, `admin-frontend`) to use the `latest` image tag
instead of a specific version.

**CI/CD Workflow Simplification:**

* Removed the `update-helm-values` and `commit-helm-changes` steps from
`.github/workflows/semantic-release.yml`, so Helm values are no longer
automatically updated and committed during release.
* Removed the summary line indicating the Helm chart was updated from
the workflow output.
