interpreter name in kernelspec gets jumbed to python3<hash #>

[juhuebner]

possibly related to #5597 #5489

In the kernelspec section of the jupyter notebook the name of the kernel obtains an unusable name like
"name": "python388jvsc74a57bd0073360510c73ce0952195aa6ddd8e522a1bf8b6c3e24c76c079f2f34ecbdf310"
s.b.

This makes it unusable in other jupyter applications. Interestingly within vscode the notebook runs fine.

Steps to reproduce:

[NOTE: Self-contained, minimal reproducing code samples are extremely helpful and will expedite addressing your issue]

• Install at max (available higher version up-to now show the same behaviour) the Jupyter extension v2021.4.702810522

• Create a new notebook via ctrl+P + Jupiter: Create new notebook

• After saving have look at the raw content

• Some part of the long hash coincides with the fileHash located in the file kernelSpecPaths.json

• The mixed name is also changed in working notebook created with jupyter notebook if opened and saved in vscode.

Thanks for filling this issue. I'll discuss this with the team.

@juhuebner
We've decided to not store this kernel name.
We'll try to get this fix in the next release.

Validated.
