Add granular download data section to download stats docs

[julien-c]

What

Adds a new "What if I need more granular download data?" section to both the models and datasets download stats docs, pointing users to Publisher Analytics and its granular logs feature.

Changes

• models-download-stats.md: new section on getting granular, request-level download data (distinguish config.json from weights, exclude CI/CD, deduplicate users).
• datasets-download-stats.md: equivalent section adapted for datasets.
• Links to Publisher Analytics are relative (./publisher-analytics), matching the in-repo doc style.

Note

Low Risk
Documentation-only additions with no runtime or security impact.

Overview
Adds a “What if I need more granular download data?” section to both models-download-stats.md and datasets-download-stats.md, so readers know how to go beyond default Hub download counters.

Each page lists typical needs (e.g. split file types, drop CI/CD traffic, unique downloaders) and points to Publisher Analytics and its granular logs anchor for anonymized, request-level logs across an org’s models and datasets. The models doc calls out config.json vs weights; the datasets doc calls out data vs metadata. Both note that logs are raw so orgs can apply their own rules. Links use relative ./publisher-analytics paths consistent with neighboring hub docs.
