Only use automated years in titles in old charts

[edomt]

In some charts from old times years are hard-coded in the title – in those cases we should delete them from the title, and use the automated time instead.

Can be found with

SELECT id
FROM charts
WHERE JSON_extract(config, "$.title") regexp ".*[0-9]{4}.*"
  AND JSON_extract(config, "$.hideTitleAnnotation") = TRUE;

Fixed for ~200 charts today.
