docs: callout Python>=3.11 requirement on Universal MCP install snippet

Browse Source 
User-reported friction: pip install molecule-ai-workspace-runtime on a
3.10 interpreter fails with "Could not find a version that satisfies the
requirement (from versions: none)" — pip's requires_python filter
silently drops the only available artifact before attempting install,
so the error doesn't mention Python at all. Operators see
"package missing", file a bug, and chase a phantom CDN/visibility
issue.

Two changes mirror the requirement at the two operator-touch surfaces:

1. workspace-server/internal/handlers/external_connection.go:
   the externalUniversalMcpTemplate snippet (rendered into the
   canvas Connect-External-Agent modal) now leads with a brief
   "Requires Python >= 3.11" block + diagnostic + upgrade paths.

2. docs/workspace-runtime-package.md: same callout at the top of
   the doc, before the Overview, so anyone landing here from search
   gets the answer immediately.

# Workspace Runtime PyPI Package
## Requires Python >= 3.11
The wheel pins `requires_python>=3.11`. On Python 3.10 or older, `pip install
molecule-ai-workspace-runtime` fails with `Could not find a version that
satisfies the requirement (from versions: none)` — the pin filters the only
available artifact before pip even attempts install. Upgrade the interpreter
(`brew install python@3.12` / `apt install python3.12` / etc.) or use a
3.11+ venv.
## Overview
The shared workspace runtime infrastructure has **one editable source** and
