Add Matomo analytics tracking

[Copilot]

Adds Matomo analytics tracking to all documentation pages, connecting to openms.matomo.cloud with site ID 2.

Changes

• _static/js/matomo.js: New JavaScript file containing the Matomo tracking code for page views and link tracking
• docs/conf.py: Added matomo.js to html_js_files for automatic inclusion in all generated pages

Notes

The documentation now includes both Piwik Pro (piwik.js → openms-web.piwik.pro) and Matomo (matomo.js → openms.matomo.cloud) tracking.
