Converting `toml` dependency to `tomllib`

`toml` project has not had activity in quite a while and downstream packagers have already deprecated it and it will be removed from Fedora soon.

As poetry is a barrier of contribution, I am offering the required change to move from `toml` to stdlib `tomllib` in this issue, this should also include the dependency
```toml
dependencies = [
"tomli;python_version<'3.11'",
]
```

```patch

The proposed change targets teampulls/teampulls.py and the dependency list shown in the issue. Start by reviewing TOML loading around the path handling near line 125 and the project's supported Python versions. Run the project's existing checks, if available, and confirm malformed TOML still produces the documented error.
