No event page for Hausa translation

[TimOsahenru]

When you visit this URL https://blackpythondevs.com/ha/events/ it returns a 404 error page . To fix this, create an events.md file in the _article/ha directory, the content could be in English for now

We could have the events page in English for now, till we can translate to Hausa instead of returning a 404 error page. @kjaymiller please assign this to me if that's fine
