pypi - Failed to process PriorityResourceURI

The pull request https://github.com/aboutcode-org/purldb/pull/600 allows to use the `api/collect/index_packages/` API endpoint for pypi packages. I have encountered an error while doing so, which seems to indicate that some data is longer than the database column permits.

```

The above exception was the direct cause of the following exception:
