[FW][REM] crm: track prospects visits

[fw-bot]

The information in this document is no longer relevant in V15+ as the Lead Scoring module was deprecated. Removed this document and added a redirect.
https://www.odoo.com/documentation/15.0/applications/sales/crm/track_leads/prospect_visits.html

Also removed doc link (and reference to the deprecated module) from Link Trackers doc https://www.odoo.com/documentation/17.0/applications/websites/website/reporting/link_tracker.html#follow-up-on-tracked-links

Should only need a tech review since there were no content changes.
