Limit Summary of Changelog Text to Ensure it can be posted to twitter

[smeubank]

Steps to Reproduce

1. post to the changelog with a summary and title text which is more than the free tier of a tweet/x-post
2. look at the x account for auto-posting our new changelogs
3. it will not be there

Expected Result

It should be there

Actual Result

It will not be there

Additional Info

We need to consider to add a limit to the concatenated character count of the title and summary fields to ensure it will always be postable to twitter

You can write as much as you like in the post, just not the summary
