chore: enable dependabot updates

[agent-werner]

Adds Dependabot version update configuration for detected package ecosystems and GitHub Actions.

[greptile-apps]

Greptile Summary

This PR adds a Dependabot configuration file that enables automated dependency updates for the github-actions ecosystem (root) and the npm ecosystem across all four directories that contain a package.json (/, /docs, /packages/python2ts, /packages/pythonlib). All referenced directories exist in the repository, schedules are consistent (weekly on Mondays at 06:00 Europe/Berlin), and each block groups all updates into a single PR to reduce noise.

Confidence Score: 5/5

This PR is safe to merge — it only adds a configuration file with no impact on runtime code.

The change is a single, well-formed Dependabot YAML file. All referenced directories exist, the ecosystems match the actual package files in the repo, and no code is modified. No issues found.

No files require special attention.

Important Files Changed

Filename	Overview
