Fix entity escaping in rss.xml

Fixes the entity escaping in the RSS item description. Uses the same escaping mechanism as the default Hugo rss template.

transform.XMLEscape requires Hugo 0.121.0 or newer. https://gohugo.io/functions/transform/xmlescape/

What's your policy on the Hugo version? I see the netlify bot is currently building with 0.115.4.

An alternative fix could be to use | html as in older versions of the default hugo template: gohugoio/hugo@b4c5df4#diff-76032d349eedf06717453a1b01a0ebab2b4324b19533b2825f18eb9a2a377e6b

@cjyabraham - just curious, why you're not using the Hugo RSS template?

Tbh, I can't remember now, but pretty sure it wasn't showing the content I wanted it too. I can try switching back if I get time. Also @woefe thanks for your PR, and sorry for not approving it yet, I haven't had a chance to work on this theme recently.

Thanks for this, will be released in v0.1.5 of the theme
