Suggest pinned package dependency updates on pyproject.toml

[jzazo]

I am not sure what the best practice would be, but for certain packages I would like these packages to be pinned to the latest published versions, specially if installing dev versions of those packages (e.g., pytorch nightly versions, sometimes latest stable, etc.).

The feature request is that if pyproject.toml has pinned dependencies, that suggestions to update pins are made when new versions are released.

I believe a similar feature exists in Pycharm, although not entirely sure. Thanks.
