v1.2.0

Highlights

1. Don't use symbolic links internally.
   This fixes a couple of issues with Node.js tools on Windows:
   • Developer Mode is no longer needed.
   • The build_js() and build_sass() functions now work with watch = TRUE.
   • The lint_js() function now works when imports are used in JavaScript.
2. Drop dependency on Yarn - only Node.js is now required.
3. Improved Rhino CI:
   • Run build_js() and build_sass() CI.
   • Use R version from the lockfile.
   • Upgrade to r-lib/actions/setup-r@v2.
4. The lint_r() now accepts a paths argument which can be used to run it on specific files.
5. The init() function will refuse to run in the home directory unless force = TRUE is passed.
6. Shiny bookmarking works better with legacy_entrypoint: source
   (the UI function no longer needs to take an argument).
7. Upgraded to lintr >= 3.0.0 and updated linter rules.
