Drop @public on names already exported via ModelingToolkitBase reexport

`hasdescription`, `getdescription`, `hasmisc`, `getmisc` are exported
into Catalyst's namespace through `@reexport using ModelingToolkitBase`,
so declaring them `public` is a load error:

  cannot declare Catalyst.hasdescription public; it is already declared exported

The original export-scan only parsed Catalyst's own `src/` `export` lines and
missed reexported names. Remove the four reexport-exported names from the
`@public` additions; the remaining 21 documented, non-exported names stay.
Verified `using Catalyst` loads cleanly on Julia 1.12.
