Fix markitdown MCP server schema validation failure

[Copilot]

The MCP Inspector workflow failed during gateway initialization because the markitdown server configuration violated the MCP Gateway schema. Stdio servers must use container field, not command.

Error:

Error: doesn't validate with '/definitions/stdioServerConfig'
- missing properties: 'container'
- additionalProperties 'command' not allowed

Changes:

• Updated .github/workflows/shared/mcp/markitdown.md to use official Docker image
• Removed pip installation step (no longer needed with containerization)
• Recompiled affected workflows (mcp-inspector, pdf-summary, scout)

Before:

steps:
  - name: Install Markitdown MCP
    run: pip install markitdown-mcp
mcp-servers:
  markitdown:
    command: "markitdown-mcp"
    allowed: ["*"]

After:

mcp-servers:
  markitdown:
    container: "mcp/markitdown"
    allowed: ["*"]

Note: Other command-based configs (fabric-rti, sentry) are auto-transformed by the compiler's getWellKnownContainer function. markitdown-mcp was not in the known list, requiring explicit containerization.
