Assorted improvements for our platform EOL check code. (#14768)

* Fix typos in EOL check matrix generation.

* Allow specifying a different name for distro for EOL check.

If the `eol_check` property of a distro entry is a string, use that as
the product name when querying https://endoflife.date/api

* Add failure notifications for scheduled runs of EOL check workflow.
