deps(ci): update Dependabot, pre-commit tooling, and testing dependencies (#5170)

# Description of Changes

This pull request updates dependency management and CI/CD configurations
to improve automation, security, and maintainability. The most
significant changes include expanding Dependabot coverage to more
directories and ecosystems, updating pre-commit and Python dependency
versions, and pinning action versions in GitHub workflows for better
reproducibility and security.

**Dependency Management Improvements:**

* Expanded Dependabot configuration in `.github/dependabot.yml` to
include additional directories and package ecosystems such as npm,
docker, cargo, and pip, ensuring automated dependency updates across
more parts of the project.
* Updated Python dependencies in
`.github/scripts/requirements_pre_commit.txt` to newer versions for
`cfgv`, `filelock`, `platformdirs`, `pre-commit`, and `virtualenv`,
improving compatibility and security.

* Added `tomli-w` to `.github/scripts/requirements_sync_readme.in` and
`.github/scripts/requirements_sync_readme.txt` for TOML file writing
support.

**CI/CD Workflow Enhancements:**

* Updated installation commands in `.github/workflows/check_toml.yml`
and `.github/workflows/sync_files_v2.yml` to use hashed and
version-pinned dependencies, improving reproducibility and security.
Also removed redundant dependency installation in the sync workflow.

* Pinned GitHub Actions versions in
`.github/workflows/deploy-on-v2-commit.yml` by using commit SHAs for
actions such as `actions/checkout`, `docker/setup-buildx-action`,
`docker/login-action`, and `docker/build-push-action`, ensuring builds
use known-good versions.

**Pre-commit Configuration Updates:**

* Updated hooks in `.pre-commit-config.yaml` to newer versions for
`ruff-pre-commit`, `gitleaks`, and `pre-commit-hooks`, providing
enhanced linting and security scanning.
