Update duolingo pre-commit hook to 1.8.0 (TOOLS-581)

[artnc]

Description

This yearly upgrade does the following and should be pretty safe:

• Adds support for autoformatting Go, C++, TOML
• Reduces the Docker image size by 60%
• Updates Prettier/Ruff/ktfmt/etc to their latest versions
  • Most notable new feature: Kotlin trailing commas
• Updates Splinter (if present) to respect splinter:ignore comments
