Recaptcha for contact forms

We have added recaptcha mechanism as an optional feature on contact pages, to prevent bots from submitting contact forms:

The recaptcha mechanism's version is V3, which means no tedious image classifications, or checking checkbox "I'm not a robot". Instead, end user behaviour is analysed and form submissions get a score from 0 to 1, where 0 means it's 100% a bot and 1 means it's 100% a human. Thanks to the score we can come up with a cut-off value that is specific to your area/website and based on that cause some actions (eg. notifications).
