Automation to get new playwright version PR.

[digitronik]

Old: detect new version → create git tag → trigger build-and-publish.yml → build & push to Docker Hub

New: detect new version → update PLAYWRIGHT_VERSION/PLAYWRIGHT_MINOR_VERSION in Dockerfile → open a PR → maintainer merges → Konflux Tekton pipeline builds & releases

I looked at your PR and whole .github/workflows/check-playwright-version.yml file can be replaced most probably with Renovate/Mintmaker.

something like this -> renovate.json created in root of this repository:

 {
    "$schema": "https://docs.renovatebot.com/renovate-schema.json",
    "customManagers": [
      {
        "customType": "regex",
        "fileMatch": ["^docker/Dockerfile\\..*$"],
        "matchStrings": [
          "ARG PLAYWRIGHT_VERSION=(?<currentValue>\\d+\\.\\d+\\.\\d+)"
        ],
        "depNameTemplate": "playwright",
        "datasourceTemplate": "npm",
        "extractVersionTemplate": "^(?<version>.*)$"
      }
    ]
  }

Regarding PLAYWRIGHT_MINOR_VERSION, I believe we can extract this in the Dockerfile?
We can configure this ^ check to be running every 4 hours or based on some schedule. What do you think?
