Checkbox validation for subscriptions en legal consent

Problem/Motivation

Legal consent and subscription fields that are conditionally mapped to a Webform checkbox are not being processed in HubSpot.

The legal consent and subscription logic introduced in #3229134: Add support for legalConsentOptions checks if the value == 1. However the changes in #3212295: Webform to HubSpot Checkbox mapping does not work updated checkbox values to return strings true and false.

Also the legal consent and subscription logic is for the checkbox and webform_terms_of_service field. The true and false update is only for the checkbox.

Steps to reproduce

HubSpot

1. Create a new form
2. Add a new component to the form: Data Privacy (other)
3. Add a Subscription for checkbox (1)

Drupal

1. Add a new checkbox field
2. Setup a handler on a webform
3. Add a subscription which is 'Conditionally' linked to the new checkbox
4. Test the form and don't check the checkbox
5. View the submission or contact to review the subscription: the subscriptions are not added

Proposed resolution

• The check should be updated to support the new string (true and false) values.
• Add webform_terms_of_service to the array
