testing/hurl: delete python3 dev dependencies
Hi, I'm on of the maintainer of Hurl. In the APKBUILD of Hurl, there is a dev dependency on Python3 that is not necessary. The man file hurl.1 and hurlfmt.1 used to be build with Python. No, we commit the manual files in the repo so there is no need to rebuild it (we've made it mainly to make life easier on packages maintainers)
