docs: align botasaurus + auto fallback + web release model

[gildesmarais]

Summary

• update Ruby gem docs to include botasaurus strategy coverage
• simplify high-level wording to JavaScript/browser-based extraction while keeping concrete strategy details in reference pages
• document CLI default fallback order: faraday -> botasaurus -> browserless
• add BOTASAURUS_SCRAPER_URL guidance in strategy/CLI/troubleshooting docs

Why

This docs update tracks the Botasaurus strategy introduction in html2rss core:

• feat(strategy): add Botasaurus strategy html2rss#357

and new default auto strategy:

• feat: make strategy optional + default to :auto with fallback selection & raise on empty feed html2rss#358

Validation

• npm run -s build

Pull request overview

Updates the documentation site to reflect new html2rss strategy behavior (Botasaurus + auto fallback) and the html2rss-web Docker release/tagging model, while simplifying some high-level onboarding copy.

Changes:

• Document default auto strategy fallback order (faraday -> botasaurus -> browserless) and add BOTASAURUS_SCRAPER_URL guidance across strategy/CLI/troubleshooting docs.
• Switch recommended html2rss-web Docker image usage from :latest to the major-version tag :1, and document the tagging scheme.
• Simplify web-app onboarding and deployment wording; update Watchtower guidance to emphasize “updates follow the tag”.
