Example for Organisation or User project has repo project URLs

[cpswan]

In README.md the Organisation or User project example has project: URLs for repo projects rather than Organisation or User:

      with:
        project: 'https://github.com/srggrs/assign-one-project-github-action/projects/2'

rather than something like:

      with:
        project: 'https://github.com/orgs/srggrs-org/projects/1'

or

      with:
        project: 'https://github.com/users/srggrs/projects/1'

Yeah I know I need to improve the README and the instructions on the PAT (token)
