ci: fixes bot workflow and comment update

[aeddi]

This PR should (normally) fix the issues with the bot on this repo.
In addition to the fixes, I also replaced the old config with a config that has much simpler rules while we decide what to add later on, once we've verified that everything is working properly.

Here is the current config, If nothing seems off to you, we can merge it as it is then improve it incrementaly.

auto := []automaticCheck{
  {
    description: "Maintainers must be able to edit this pull request",
    ifC:         c.Always(),
    thenR:       r.MaintainerCanModify(),
  },
  {
    description: "The pull request head branch must be up-to-date with its base",
    ifC:         c.Always(),
    thenR:       r.UpToDateWith(gh, r.PR_BASE),
  },
  {
    description: "Changes to 'docs' folder must be reviewed/authored by at least one devrel and one tech-staff",
    ifC:         c.FileChanged(gh, "^docs/"),
    thenR: r.Or(
      r.And(
        r.AuthorInTeam(gh, "devrels"),
        r.ReviewByTeamMembers(gh, "tech-staff", 1),
      ),
      r.And(
        r.AuthorInTeam(gh, "tech-staff"),
        r.ReviewByTeamMembers(gh, "devrels", 1),
      ),
    ),
  },
}

manual := []manualCheck{
  {
    description: "The pull request description provides enough details",
    ifC:         c.Not(c.AuthorInTeam(gh, "core-contributors")),
    teams:       Teams{"core-contributors"},
  },
  {
    description: "Determine if infra needs to be updated before merging",
    ifC: c.And(
      c.BaseBranch("master"),
      c.Or(
        c.FileChanged(gh, `Dockerfile`),
        c.FileChanged(gh, `^misc/deployments`),
        c.FileChanged(gh, `^misc/docker-`),
        c.FileChanged(gh, `^.github/workflows/releaser.*\.yml$`),
        c.FileChanged(gh, `^.github/workflows/portal-loop\.yml$`),
      ),
    ),
    teams: Teams{"devops"},
  },
