include highlights to non-gift & gift shares

[MMSaleh-FT]

This PR updates the behaviour of x-gift-article component to add the option to include highlights when using gift & non-gift sharing for B2B users. The new logic is as follows:

• Option to 'include highlights' has been added to the share modal for gift article and non-gift share
• If a B2B user selects 'include highlights', a highlight share token is generated via the Professional user-annotations-api
• The highlights token is appended as a query param to the share url, along with the article share token, and is then shortened by bit.ly before being returned to the user
