ORG NAME CHANGE]: Update repo to hubverse-org organisation name

[annakrystalli]

:exclamation: Please do not merge anything into main until the 19th June

• [x] Create new branch called to-hubverse from latest dev branch (most likely related to the v3 schema PRs). (Make sure to pull first). If none exist, branch off from main.
• [x] Find and replace Infectious-Disease-Modeling-Hubs with hubverse-org throughout repo.
• [x] Fork ci-testhub-simple to ci-testhub-simple-old-orgname that will remain with old orgname
• [x] Copy PR tests and also run against ci-testhub-simple-old-orgname to track back-compatibility
• [x] Update snapshots once schema is released and new version of hubAdmin released
• [x] Replace origin remote to point to the new organisation

  git remote set-url origin https://github.com/hubverse-org/<REPO_NAME>.git
  # Check remotes
  git remote -v

  url <- paste0('https://github.com/hubverse-org/', basename(getwd()), '.git')
  usethis::use_git_remote(name = "origin", url, overwrite = TRUE)
  # Check remotes
  usethis::git_remotes()

• [x] Push and open PR to original branch.
• [x] Remove refs from dependencies
• [x] Re-run tests when hubAdmin released
