Fix double-escaping of the curl and Python example code (#709)

* Fix double-escaping of the curl and Python example code

These code fragments are escaped when they are substituted into the
`silk/request.html` template, so they should not be escaped an extra time
when they are constructed.

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci
