Fix debian Github action job

[ggbecker]

Description:

• Add pyyaml package to pip package list and use a specific version of it that is known to work.

Rationale:

• Older version of pyyaml can cause the following issue:

Traceback (most recent call last):
  File "/__w/content/content/build-scripts/compile_all.py", line 136, in <module>
    main()
  File "/__w/content/content/build-scripts/compile_all.py", line 132, in main
    save_everything(args.resolved_base, loader, profiles_by_id.values())
  File "/__w/content/content/build-scripts/compile_all.py", line 108, in save_everything
    loader.save_all_entities(base_dir)
  File "/__w/content/content/ssg/build_yaml.py", line 1703, in save_all_entities
    self.save_entities(self.all_rules.values(), destdir)
  File "/__w/content/content/ssg/build_yaml.py", line 1721, in save_entities
    entity.dump_yaml(dest_filename)
  File "/__w/content/content/ssg/build_yaml.py", line 330, in dump_yaml
    yaml.dump(to_dump, f, indent=4, sort_keys=False)
  File "/usr/lib/python3/dist-packages/yaml/__init__.py", line 200, in dump
    return dump_all([data], stream, Dumper=Dumper, **kwds)
TypeError: dump_all() got an unexpected keyword argument 'sort_keys'

@mdedonno1337 FYI

@mdedonno1337 this seems to work just fine. I'm merging this (Forgot I cannot self-merge, let's ping someone else). If you don't agree with the fixed version for the pyyaml package we can change it later, but at least we'll keep the job passing now.

@yuumasato @jan-cerny can you guys please merge this one? Thanks

[mdedonno1337]

OK for me.
I will keep an eye on this and try with the version 6.
Thanks!
