[INFRA-414] feat: add DRAWIO_EMBED_URL env to plane-enterprise chart

[akshat5302]

Description

Adds the DRAWIO_EMBED_URL environment variable (default empty) to the plane-enterprise chart so operators can point the Wiki editor's diagram extension at a self-hosted drawio endpoint instead of the diagrams.net cloud.

• templates/config-secrets/app-env.yaml — renders DRAWIO_EMBED_URL into the app-vars ConfigMap, alongside other API settings (SENTRY_DSN, INTAKE_EMAIL_DOMAIN, etc.).
• values.yaml — adds env.drawio_embed_url: '' with a documenting comment.

When empty, the backend defaults to the diagrams.net cloud, so this is a safe, non-breaking addition. Mirrors the same change made across the docker-compose deployments.

Verified with helm template — renders DRAWIO_EMBED_URL: "" by default.

Community (plane-ce) chart intentionally untouched: drawio is an EE feature.

Walkthrough

A new drawio_embed_url configuration key is added to the Helm chart, allowing operators to specify a self-hosted draw.io endpoint URL. The value is defined in values.yaml with an empty-string default, wired into the app-env ConfigMap template as the DRAWIO_EMBED_URL environment variable, documented in the README, exposed as a UI configuration prompt in questions.yml, and the chart version is incremented to 2.5.2.

Configuration value and ConfigMap wiring charts/plane-enterprise/values.yaml, charts/plane-enterprise/templates/config-secrets/app-env.yaml	drawio_embed_url is declared in values.yaml with an empty-string default and comments; the app-env ConfigMap template reads .Values.env.drawio_embed_url and emits it as DRAWIO_EMBED_URL, defaulting to "" when unset.
Documentation and UI configuration charts/plane-enterprise/README.md, charts/plane-enterprise/questions.yml, charts/plane-enterprise/Chart.yaml	README.md documents env.drawio_embed_url as an optional setting for self-hosted draw.io endpoints; questions.yml adds a UI prompt ("Drawio Embed URL") for operator configuration during deployment; chart version bumped from 2.5.1 to 2.5.2.

A rabbit hops through configs with glee,
Adding draw.io URLs, one, two, three!
🐇 Self-hosted or cloud, the choice is yours,
Just set the value and open the doors.
Empty string means diagrams.net flies free! ✏️
