Markdown hover text without language spec keep code fences

[oliverralbertini]

I have an LSP (pyre code-navigation) returning code-fenced hover contents without a language specified, e.g.

"response": {"contents": "```\nFoobar\n```"}

Other LSPs may respond like this:

"response": {"contents": "```python\nFoobar\n```"}

Currently that means the backticks/code fences are not removed, so I see in the message bar 3 backticks, and if I hover into a floating window, I get the code + code fences, e.g.

```
Foobar
```
