Specify black version 23.7.0 to resolve a release build issue

[TamiTakamiya]

Small changes in a dependent library version (black) for resolving a release build issue.

    The conflict is caused by:
        black-pre-commit-mirror 0.1.0 depends on black==23.7.0
        The user requested (constraint) black==23.9.1
    
    To fix this you could try to:
    1. loosen the range of package versions you've specified
    2. remove package versions to allow pip attempt to solve the dependency conflict
stderr:
    ERROR: Cannot install black-pre-commit-mirror==0.1.0 because these package versions have conflicting dependencies.
