Update source branch refs from master to main

[justin808]

Summary

• The react_on_rails repo renamed its default branch from master to main
• Updates the editUrl in docusaurus.config.ts to point to main
• Updates the changelog link in sidebars.ts to use main
• Updates the default clone ref in sync-docs.mjs from master to main

Without this fix, "Edit this page" links, the changelog link, and doc syncing all point to the now-stale master branch.

Test plan

• Verify "Edit this page" links on doc pages resolve correctly
• Verify the "Full Changelog (GitHub)" sidebar link works
• Run npm run sync-docs and confirm it clones from the main branch

Note

Low Risk
Low risk: this only updates branch names used for doc sync and external GitHub links, with no runtime logic changes beyond which ref is cloned/linked.

Overview
Updates all docs-related references from master to main for the upstream react_on_rails repo.

This changes the GitHub Actions site build/deploy workflow to sync docs from main, updates Docusaurus editUrl and the sidebar changelog link to point at main, and adjusts scripts/sync-docs.mjs to default to cloning main when no local docs repo is present.

Poem

🐰 From master to main we hop and bound,
Three little changes, all so sound,
Branches renamed, a cleaner sight,
Our documents dance in the main branch light,
Simple, swift, and oh so right! 🌳

In `@scripts/sync-docs.mjs`:
- Line 118: CI still forces REACT_ON_RAILS_REF=master so your new fallback to
"main" is ignored; update the workflow to align with the code change by changing
the REACT_ON_RAILS_REF environment value from "master" to "main" in both Sync
docs steps (the Sync docs step in the build job and the Sync docs step in the
deploy job) so the automated sync uses the "main" branch when the env is set in
the script.
