Export fails due to urllib3 version mismatch

I'm using version 1.5.0 of this plugin.

$ poetry --version   
Poetry (version 1.5.1)

$ poetry export -f requirements.txt --without-hashes -o requirements/prod.txt 

The `urllib3` package has the following compatible candidates `[Package('urllib3', '1.26.17')]`;  
but, the exporter dependency walker previously elected `urllib3 (2.0.6)` which is not compatible 
with the dependency `urllib3 (>=1.25.4,<1.27)`. Please contribute to `poetry-plugin-export` to 
solve this problem.

$ poetry self add urllib3   
Using version ^2.0.6 for urllib3

Updating dependencies
Resolving dependencies... (0.0s)

Because poetry-instance depends on poetry (1.5.1) which depends on urllib3 (>=1.26.0,<2.0.0), 
urllib3 is required. So, because poetry-instance depends on urllib3 (^2.0.6), version solving failed.

Not quite sure how I could contribute..

Reproduce the failure with Poetry 1.5.1 and poetry-plugin-export 1.5.0 using the shown poetry export command. Start by tracing the exporter dependency walker and its handling of the compatible urllib3 candidates; done means the export completes without selecting an incompatible version.
