[BUG] AssertionError when using with httpdomain extension

[danielnelson]

Describe the bug

When building docs with this httpdomain directive, which is their basic usage example:

.. http:get:: /users/(int:user_id)/posts/(tag)

I get this error:

  File "/home/dbn/usr/py-3.12/lib/python3.12/site-packages/docutils/nodes.py", line 199, in walkabout
    visitor.dispatch_departure(self)
  File "/home/dbn/usr/py-3.12/lib/python3.12/site-packages/sphinx/util/docutils.py", line 599, in dispatch_departure
    method(node)
  File "/home/dbn/usr/py-3.12/lib/python3.12/site-packages/sphinx_markdown_builder/translator.py", line 159, in _pop_context
    ctx.add(last_ctx.make(), last_ctx.params.prefix_eol, last_ctx.params.suffix_eol)
  File "/home/dbn/usr/py-3.12/lib/python3.12/site-packages/sphinx_markdown_builder/contexts.py", line 135, in add

  File "/home/dbn/usr/py-3.12/lib/python3.12/site-packages/sphinx_markdown_builder/contexts.py", line 115, in force_eol
    missing_eol = self._count_missing_eol()
                  ^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/home/dbn/usr/py-3.12/lib/python3.12/site-packages/sphinx_markdown_builder/contexts.py", line 94, in _count_missing_eol

  File "/home/dbn/usr/py-3.12/lib/python3.12/site-packages/sphinx_markdown_builder/contexts.py", line 82, in _iter_reverse_char

                          ^^^^^^^^^^^^
  File "/home/dbn/usr/py-3.12/lib/python3.12/site-packages/sphinx_markdown_builder/contexts.py", line 189, in content
    assert self.is_parameter
AssertionError

If I modify the line like so, then the error no longer occurs.

- .. http:get:: /users/(int:user_id)/posts/(tag)
+ .. http:get:: /users/(user_id)/posts/(tag)

To Reproduce Steps to reproduce the behavior:

1. Install packages sphinxcontrib-httpdomain
2. Add it to the sphinx extensions:

   extensions = [
      "sphinx_markdown_builder",
      "sphinxcontrib.httpdomain",
   ]

3. sphinx-build -M markdown docs _build

Expected behavior Successful documentation build

Environment (please complete the following information):

• OS: Gentoo; Python 3.12
