Fix the release flow

[Adamantios]

Proposed changes

This PR fixes a typo in the release flow that caused the specified Python version to be ignored, resulting in the default version being used instead.

As a result, failures occurred because the project's Pipfile expects Python 3.10 to be present in the system.

With this fix, the correct Python version will be properly recognized, ensuring the release flow runs as expected.
