Add SENTRY_DSN authentication to Sentry MCP server configuration

[Copilot]

The nightly stress test detected that the Sentry MCP server requires SENTRY_DSN for authentication but the workflow configuration was missing this environment variable.

Changes

Added environment variable configuration to the sentry MCP server in .github/workflows/nightly-mcp-stress-test.md:

sentry:
  type: stdio
  container: "mcp/sentry"
  env:
    SENTRY_DSN: "${{ secrets.SENTRY_DSN }}"

This follows the same pattern as other authenticated servers (e.g., github server with GITHUB_PERSONAL_ACCESS_TOKEN).

Required Follow-up

Repository administrators must add SENTRY_DSN secret containing a valid Sentry DSN from Project Settings > Client Keys.
