docs: kdoc: some fixes to kernel-doc comments

There are some typos and English errors in the comments of kernel‑doc.py.

Locate them with the help of an LLM (gpt‑oss 14B), executed locally
with this prompt:

        review English grammar and syntax at the comments on the code below:
        <cat scripts/kernel-doc.py>

While LLM worked fine for the task of doing an English grammar review
for strings, being able to distinguish them from the actual code, it
was not is perfect: some things required manual work to fix.

-

While here, replace:

    "/**" with: ``/**``

As, if we ever rename this script to kernel_doc.py and add it to
Sphinx ext autodoc, we want to avoid this warning:

    scripts/kernel_doc.py:docstring of kernel_doc:10: WARNING: Inline strong start-string without end-string. [docutils]
