Update eol_data for API changes

The endoflife.date API has been updated, so this modifies the URL in
`SharedAudits.eol_data` to use the up to date URL and modifies the
related logic in `FormulaAuditor.audit_eol` to work with the new
response format. Specifically, there is now an `isEol` boolean value
and the EOL date is found in `eolFrom`.

One wrinkle of the new setup is that 404 responses now return HTML
content even if the request includes an `Accept: application/json`
header. This handles these types of responses by catching
`JSON::ParserError` but ideally we would parse the response headers
and use `Utils::Curl.http_status_ok?` to check for a good response
status before trying to parse the response body as JSON.
