refresh isn't going anywhere, but sync will be the canonical command
here on out, because it is more appropriate for kind of work it will be
doing in the future.
- Renamed doom/open-vanilla-sandbox to doom/sandbox (because it's not
just for vanilla testing anymore)
- Renamed doom/open-bug-report to doom/report-bug (for consistency with
`report-emacs-bug`; makes it easier to discover)
- Add SPC h d b for doom/report-bug
- Add SPC h d s for doom/sandbox
Can now launch four different sessions:
1. Vanilla Emacs
2. Vanilla Doom (only Doom core)
3. Doom core + modules - private config
4. A full Doom session (load everything)
This adds the option to run elisp in an environment where doom core &
modules are loaded, but not your private modules or config.
Also updates the vanilla sandbox text template.
