fix(otel): OPENFGA_TRACE_OTLP_TLS_ENABLED boolean flag quote

[yannchabed]

This PR ensures that the OPENFGA_TRACE_OTLP_TLS_ENABLED environment variable is correctly handled as a boolean string within the Helm chart templates.

Description

What problem is being solved?

In the current Helm chart, the OPENFGA_TRACE_OTLP_TLS_ENABLED variable—used to toggle TLS for OpenTelemetry Protocol (OTLP) tracing—was not being correctly processed. In Kubernetes manifests, environment variable values must be strings. If a boolean (true/false) is passed directly from Helm's values.yaml without explicit casting or quoting, it causes template rendering errors or be misinterpreted by the OpenFGA server at runtime.

How is it being solved?

The issue is resolved by updating the deployment template to ensure that the value of OPENFGA_TRACE_OTLP_TLS_ENABLED is explicitly converted to a string (quoted) before being injected into the container environment. This ensures compatibility with Kubernetes API expectations and OpenFGA's configuration logic.

What changes are made to solve it?

• Updated templates/deployment.yaml to include the OPENFGA_TRACE_OTLP_TLS_ENABLED environment variable.
• Applied the quote function surround the value with double quotes to ensure boolean inputs from values.yaml are rendered as "true" or "false".
• Aligned the OTLP TLS configuration with the standard environment variable patterns used elsewhere in the chart.

This is a very small update. But necessary for a clean OTEL deployment.
