Rename "Checks" to "Alerts"?

Docs mostly use the term "Checks" in page titles and headings in the Monitoring and Alerts section.
In the UI nav, the feature is "Alerts".
For the UI, Docs "Checks" guides describe how to use the "Alerts" in the UI., e.g. https://docs.influxdata.com/influxdb/v2.4/monitor-alert/checks/create/.
Search for "alerts" does a poor job of returning Checks pages.

Review the linked Checks guide and search the documentation for page titles, headings, and references to “Checks” and “Alerts.” First determine whether the terminology should be changed and which pages are in scope; done means the agreed terminology is applied consistently and the relevant pages are discoverable through an Alerts search.
