Update job_detail.html

[joncle]

Explicity escape the job description for the meta og:description where the description contains html which can throw off the rendering of the page...

See https://www.python.org/jobs/7314/ for example.

This should close #2020 for now

Alternatively - it might be better to escape after truncating {{ object.description|truncatechars:200|escape }} at the risk of going over 200 characters but at least then it wouldn't run the risk of truncating escape sequences although I think that's less of a potential issue than having the meta tag bleed html into the page... happy with either.

This seems it did not do the thing needed to fix as examples in #2307 and #2020 remain.
