Include missing files in reh-web binary (#4761)

- Part of #4274
- Adds missing files to the includes: a new file (rsLoginCheck.js) from
Workbench via #4655 and the help.html help container page

### QA Notes

When running Positron in Workbench, there should be no server or dev
console errors around missing these files. Positron should load in
Workbench.
