Show `CHANGES` in RSS Content

[rwp0]

Not sure if it's the right repository to report this issue, but currently the feed content (ie. body) is always the description of the distribution which very rarely change.

I propose instead putting CHANGES since every version the distribution released gets a new feed.

Example distribution: https://metacpan.org/release/PEVANS/Object-Pad-0.813

RSS body (Feedly):

I have to click and open in (external) web browser to see what's new with the distribution.

MetaCPAN parses the CHANGES file and display for every version as can be seen in the image above.

This good dynamic (instead of constant description) behavior can be utilized in the RSS feed content as well benefitting the user trying to see the updates quickly on their followed distributions.

And if there's no CHANGES (which is a bad practice), then may fallback to distribution description.

Thanks!
