Link to a helpful FAQ in the error message "Oops, there was a problem during the request." #15135

Often Matomo users who haven't yet setup Cron + Disable browser trigger archiving,

It would be great to link from this message to the FAQ that explains this issue: https://matomo.org/faq/troubleshooting/faq_19489/

Maybe with append a text like <a href='https://matomo.org/faq/troubleshooting/faq_19489/'>See the steps to resolve this issue in the FAQ</a>..

Note:

• we don't want this extra text to be added on cloud. maybe we could link to the FAQ only when enable_general_settings_admin=1 or enable_plugins_admin=1
• we will soon improve the FAQ at https://matomo.org/faq/troubleshooting/faq_19489/ and make it more clear / better
