Rename "Help Center Home", add Devlog

Changes:
- index.tsx: Add a "Devlog" entry to match the navbar
- navbar and index.tsx: Rename "Help Center Home" to "Users"
- navbar: Change the leftmost entry (which points to the index) from "Solus" to "Solus Help Center"
- Rework the index grid for 3 entries

Rationale:
- "Help Center Home" is too generic, "Users" is more specific
- The actual "home" (top level page for https://help.getsol.us) is somewhere else

Bikeshedding: Suggest a better icon for "devlog" from here https://mui.com/material-ui/material-icons/?query=fe&theme=Outlined
