[Improvement]: Examples CI: Modified workflow for the develop branch

[jonaro00]

In shuttle-examples, the CI workflow for main and develop is the same.
When breaking changes are made on the develop branch, the CI checks will fail since they run against the last released versions of the shuttle crates.

The idea is to make a separate workflow for the develop branch that does the same things as the current one, but before running checks, checkout the main branch of the main repo, and run the scripts/apply-patches.sh script so that compilation will use the checked out code.

To work on this, simply open a PR to examples' develop branch, and (after we run it) you will know it works if the compilation messages say that the crates are local paths.
