Error when using the tab-size option

[MichaReiser]

Summary

This PR makes the warning when using the tab-size option an error. The tab-size option was deprecated in Ruff 0.1.2 (released October 2023).

Part of #7650

Test Plan

• Verified that the option isn't used by the LSP (I searched for tab-size and tab_size)
• Verified that the option isn't exposed via the CLI (other than using --config)
• Verified that using the previously accepted tab-size option fails

❯ ../ruff/target/debug/ruff check test.py --config tab-size=2
ruff failed
  Cause: The `tab-size` option has been renamed to `indent-width` to emphasize that it configures the indentation used by the formatter as well as the tab width. Please update your `--config` CLI arguments to use `indent-width = <value>` instead.
