workflows: let forks run their own model builds (#2009)

build-single-tinygrad-model and build-all-tinygrad-models gain a docs_repo
input (default sunnypilot/sunnypilot-models) so a fork can run either against
its own gh-pages catalog, next to the existing hf_repo input for the dataset.

build-all's setup job now checks out the repo and branch it was dispatched
from instead of sunnypilot/sunnypilot's default branch. That keeps the
manifest's tinygrad_ref tied to the code that compiled the models, and lets a
fork run the full rebuild against its own dataset and docs repo.
