faq says to use wget to get spec, but wget is not available

Ohai,

https://packit.dev/docs/faq/#how-can-i-download-rpm-spec-file-if-it-is-not-part-of-upstream-repository says that the following snippet should produce a downloaded spec file:

specfile_path: packit.spec
files_to_sync:
  - packit.spec
  - .packit.yaml
upstream_package_name: packitos
downstream_package_name: packit
actions:
    post-upstream-clone: "wget https://src.fedoraproject.org/rpms/packit/raw/main/f/packit.spec -O packit.spec"

However, when I run this in my project, I get:

2023-01-05 11:00:48.355 commands.py       DEBUG  Command: wget https://raw.githubusercontent.com/theforeman/foreman-packaging/rpm/develop/packages/foreman/rubygem-foreman_maintain/rubygem-foreman_maintain.spec -O rubygem-foreman_maintain.spec

This can be fixed by setting srpm_build_deps:

srpm_build_deps:
  - wget

but the docs don't tell one to do so.
