[REM] Sales: Removing Google Images page

[fw-bot]

Hiya, @Felicious! Super short review for you. I removed an outdated page since the information is actively wrong and it seems to be driving support calls. I will create the new page early next week.

• This PR removes the "Product images with Google Images page from saas-18.2 onward and creates a redirect link to the Barcode Lookup page
• Google Images support has been removed from Odoo for over a year now. This corrects inaccurate information in the Documentation.
• Expected positive impact on support requests related to the Google Images feature. Customers currently reach out support for assistance because the in-app experience doesn't match the documentation.
• link to the originating task

This saas-18.2 PR can be FWP up to master.

Forward-Port-Of: #17029
