A short description of the bug

Describe the bug
The urn copied from the Share button throws errors as using a : when needing a .

For example my urn copied direct from UI looks like this:
urn:li:dataset:(urn:li:dataPlatform:file,Users/cate/git/datahub/titanic_data/titanic_dataset:csv,PROD)

which throws when adding contract:

[2024-11-07 15:33:17,899] ERROR    {datahub.entrypoints:218} - Command failed: Cannot define a data contract for non-existent entity urn:li:dataset:(urn:li:dataPlatform:file,Users/cate/git/datahub/titanic_data/titanic_dataset:csv,PROD)

Which confused me for ages before I noticed the colon - works when changed to:
urn:li:dataset:(urn:li:dataPlatform:file,Users/cate/git/datahub/titanic_data/titanic_dataset.csv,PROD)

To Reproduce
Steps to reproduce the behavior:

1. Upload csv dataset from filesystem
2. Navigate to dataset in UI and copy the urn from the Share button
3. Use the urn when upsert-ing a data contract
