Add check that title matches URL

[georgik]

Please add following check before merging PRs:

URL should be created from the title by lowercasing letters, replacing spaces with dashes and removing non-standard character.

E.g.: title: "Multi-function USB Dongle based on ESP32-S3" should be transformed to content/blog/blog/multi-function-usb-dongle-based-on-esp32-s3
Proposed folder name/URL by author was esp-dongle in this case is not matching the title.

Reason for this chec: Using title, that does not match url is not accepted, because it reduces SEO.
