fix(pre-commit): remove Docker requirement for ruff hooks

[shirshanka]

Summary

• Ruff pre-commit hooks previously used language: docker_image, requiring Docker for every commit/push. When Docker is unavailable or has storage issues (e.g. ENOSPC/corrupted containerd), commits and pushes are completely blocked.
• Added a wrapper script (run_ruff.sh) that uses a local ruff install when available and falls back to the Docker image only when ruff is not on PATH.
• Updated the generator (generate_pre_commit.py) and regenerated .pre-commit-config.yaml.

Test plan

• pre-commit run ruff-check --files metadata-ingestion/src/datahub/cli/cli_utils.py passes with local ruff
• pre-commit run ruff-format --files metadata-ingestion/src/datahub/cli/cli_utils.py --hook-stage pre-push passes with local ruff
• Verify Docker fallback works when local ruff is not on PATH (e.g. PATH=/usr/bin bash .github/scripts/pre-commit/run_ruff.sh check metadata-ingestion/src/datahub/cli/cli_utils.py)

Summary by cubic

Removes the Docker requirement for the ruff pre-commit hooks so commits and pushes no longer fail when Docker is unavailable or misbehaving (e.g. ENOSPC or corrupted containerd state).

• Adds run_ruff.sh, which runs a local ruff when it's on PATH and falls back to the pinned Docker image (ghcr.io/astral-sh/ruff:0.15.22) only when it isn't.
• Warns when the local ruff version differs from the pinned 0.15.22.
• The Docker fallback runs with the host uid/gid to avoid root-owned files and .ruff_cache on Linux.
• Switches both ruff-check and ruff-format from language: docker_image to language: system and updates the generator and regenerated .pre-commit-config.yaml.
• Prints install guidance for ruff or Docker when neither is found.

PR Summary

Overview
Ruff pre-commit hooks no longer require Docker on every run. The generator now emits language: system hooks that invoke run_ruff.sh instead of the pinned ghcr.io/astral-sh/ruff:0.15.22 docker_image entries for ruff-check and ruff-format; .pre-commit-config.yaml is regenerated to match.

The new wrapper runs local ruff when it is on PATH (with a stderr warning if the version differs from 0.15.22), otherwise falls back to the same pinned image via docker run (host uid/gid, repo mounted at /src). If neither tool is available, it exits with install hints for ruff or Docker.
