[REQ][HTML] YAML multiline string formatting of descriptions should be translated to HTML

[john3300]

Is your feature request related to a problem? Please describe.

When using the literal style indicator (|) in a block scalar for a description, the formatting is ignored when inserted into HTML.

paths:
  /employees/{id}:
    get:
      description: |
        First line
        Second line

But right now this come out as First line Second line in the rendered HTML.

Describe the solution you'd like

When the literal style indicator is specified in the YAML, a <br> tag should be inserted at each newline when generating the HTML.

Additional context

Inserting <br> tags is how the Swagger UI does this and the formatting works great there.
Here's a good reference link on YAML multiline syntax.
