DOC-6304 DOC-6305 DOC-6306 DOC-6308 Client observability docs

[andy-stark-redis]

Don't be deceived by the branch name, the epic for this is actually DOC-6304 :-) node-redis will have support for this soon, but I'll make a separate PR for the docs to merge when it is released.

A few things to consider:

• I've attempted to give a brief flavour of the tracing process, but let me know if you think it's too much or not detailed enough.
• The attribute badges seem like they might be useful to users, but maybe they're intended more as an internal guide for implementation?
• I've added links to the observability docs from a few relevant places, but if you can think of any other pages that should have links then let me know.

Note

Medium Risk
Adds new site-wide shortcode + conditional JS/CSS to render a large metrics spec from JSON, which could affect build/runtime rendering and page performance if misconfigured. Content-only changes elsewhere are low risk.

Overview
Introduces Redis client observability documentation: a new overview page (/develop/clients/observability) with an auto-generated metrics reference, plus new client-specific Observability guides for go-redis and redis-py with runnable example snippets.

Adds a new otel-metric-groups shortcode backed by data/client_obs_metrics.json, along with new static/js/otel-metrics.js + static/css/otel-metrics.css and baseof.html conditional loading to render the JSON into a navigable, human-friendly metrics/attributes view.

Updates related docs to point readers at observability (error-handling logging section, Go production usage link fix, and a new Redis-Py production-usage recommendation), and adjusts clients/patterns page weight to change navigation ordering.
