Secret scanner workflow fails to checkout code when PR is from fork

[timfish]

I'm guessing the issue is caused by the fork but I'm honestly not sure why it's failing here!

@timfish Odd one. It was the fetch that was failing on repeat:
git -c protocol.version=2 fetch --no-tags --prune --no-recurse-submodules --depth=3 origin +refs/heads/feat/update-sdks*:refs/remotes/origin/feat/update-sdks* +refs/tags/feat/update-sdks*:refs/tags/feat/update-sdks*

Which itself was fine since it was properly referencing the refs from your fork. I re-ran the job and it passed without issue and that fetch returned as expected:

From https://github.com/getsentry/sentry-electron
[new branch]      feat/update-sdks -> origin/feat/update-sdks 

Your guess is as good as mine here.

The fetch depth was removed in the workflow, which should resolve any issues coming from a fork
