Bug in new markdown rendering

[garazdawi]

Describe the bug

In the new markdown rendering there is an issue when broken markdown is written.

To Reproduce**

-module(foo).
-moduledoc """

```erlang
test
``

""".

test() -> ok.

Note that the erlang code segment is not terminated properly, so it is not a code segment at all. This causes the rest of the module to be interpreted as markdown.

Expected behavior

I would have expected the markdown parser to terminate at the """ which is where the triple quoted string ends.

Actual behavior

Context

• ELP Version (output of elp version): 0.36.0
• Editor used: VS Code

Thanks for the report @garazdawi. I wonder if it's the detection of the end of the triple quoted string which is broken or if VS Code somehow gets confused by the incorrect code block terminating and keeps scanning the rest of the file despite the original boundaries. Worth investigating.

Relates to erlang-ls/grammar#18

Another similar issue occurs if you use a HTML tag in the Markdown:

-moduledoc """
<tag></tag>
""".

The rest of the module is incorrectly marked as Markdown.
