Update tool "black"

[ckunki]

PTB uses black for checking and fixing code formatting.

Lately, a security vulnerability has been reported for black: https://github.com/exasol/python-toolbox/security/dependabot/29

Updating black as requested raises formatting issues:

Warning: Python 3.10 cannot parse code formatted for Python 3.14. To fix this:

• run Black with Python 3.14,
• set --target-version to py310, or
• use --fast to skip the safety check.

Black's safety check verifies equivalence by parsing the AST, which fails when the running Python is older than the target version.
