using angle brackets inside backticks should be possible

I think #286 broke something.

When I write a paragraph like this in my template.md:

Up until now the guides assumed you passed in an array of data to the `@data` argument of `<YetiTable>`.

the result is

However, if I change <YetiTable> to YetiTable> it works fine:

So, the opening < is making things look unformatted. Basically everything gets stuck inside a single <p>.

Not sure if it is related, but using this now seems to render the component itself, when it used to render the correct code block before:

```hbs
{{#yeti-table data=data as |table|}}

  {{#table.header as |header|}}
    {{#header.column prop="firstName"}}
      First name
    {{/header.column}}
    {{#header.column prop="lastName"}}
      Last name
    {{/header.column}}
    {{#header.column prop="points"}}
      Points
    {{/header.column}}
  {{/table.header}}

  {{table.body}}

{{/yeti-table}}
