Keep running update process even if step fails

[augusto-herrmann]

The last three automatic data updates have failed because the Brazilian data update fails (the portal returns a server error).

The current Github Actions workflow makes it so that, if a step fails, the next steps are aborted.

Having separate workflows would solve that, but then we have the problem of needing to rebase the repository before merging each update. Another possible solution is to keep all updates in a single workflow, but making the subsequent steps run even if the previous ones fail.
