Incorrect "no action items from last meeting" suggestion

[travier]

In https://discussion.fedoraproject.org/t/fedora-coreos-community-meeting-minutes-2023-11-22/96760, we got two action items and they were not reported in #49 and got dropped.

Interesting, I suspect its because of the format change over from matrix?

I know the regex needs to be checked/updated to ensure that the action works with the new matrix bot. Since any changes could cause the regex to not find any action items.

With the latest changes, it seems we are still encountering an issue with the latest code.

'Failed: to get action items, check the last meeting notes.' This looks like we are bailing when fetching. So while fetching, lets also at the minimum improve the error to direct to the correct URL. To manually check.

Also while looking at the action, lets see about improving how it generates the URL.

Currently its fairly fragile and simply going back 7 days from the date. This was due to data storage changes the new matrix bot uses now. Put simply the new bot adds another directory which is a date.
