Ed Santiago e2573b734e Fix broken titles on readthedocs
Followup to #15621, which (correctly) removed parentheses from
md files. Turns out, a hidden part of our readthedocs process
depended on those parentheses. Update that step so it handles
the new, correct, <space><section-number> format.

Also update local-testing documentation in README, and clean it
up a little.

Fixes: #15822

# Podman Documentation
The online man pages and other documents regarding Podman can be found at
[Read The Docs](https://podman.readthedocs.io). The man pages
can be found under the [Commands](https://podman.readthedocs.io/en/latest/Commands.html)
link on that page.

## Manpage Syntax
The syntax for the formatting of all man pages can be found [here](MANPAGE_SYNTAX.md).
## API Reference
The [latest online documentation](http://docs.podman.io/en/latest/_static/api.html) is
automatically generated by two cooperating automation systems based on committed upstream
source code. Firstly, [the Cirrus-CI docs task](../contrib/cirrus/README.md#docs-task) builds
`pkg/api/swagger.yaml` and uploads it to a public-facing location (Google Storage Bucket -
an online service for storing unstructured data). Second, [Read The Docs](readthedocs.com)
reacts to the github.com repository change, building the content for the [libpod documentation
site](https://podman.readthedocs.io/). This site includes for the API section,
some javascript which consumes the uploaded `swagger.yaml` file directly from the Google
Storage Bucket.
Since there are multiple systems and local cache is involved, it's possible that updates to
documentation (especially the swagger/API docs) will lag by 10-or-so minutes. However,
because the client (i.e. your web browser) is fetching content from multiple locations that
do not share a common domain, accessing the API section may show a stack-trace similar to
the following:
![JavaScript Stack Trace Image](../contrib/cirrus/swagger_stack_trace.png)
If reloading the page, or clearing your local cache does not fix the problem, it is
likely caused by broken metadata needed to protect clients from cross-site-scripting
style attacks. Please [notify a maintainer](https://github.com/containers/podman#communications)
so they may investigate how/why the `swagger.yaml` file's CORS-metadata is
incorrect, or the file isn't accessible for some other reason.
## Local Testing
To build standard man pages, run `make docs`. Results will be in `docs/build/man`.
To build HTMLized man pages: Assuming that you have the
[dependencies](https://podman.io/getting-started/installation#build-and-run-dependencies)
installed, then also install (showing Fedora in the example):
```
$ sudo dnf install python3-sphinx python3-recommonmark
$ pip install sphinx-markdown-tables myst_parser
```
(The above dependencies are current as of 2022-09-15. If you experience problems,
please see [requirements.txt](requirements.txt) in this directory, it will almost
certainly be more up-to-date than this README.)
After that completes, cd to the `docs` directory in your Podman sandbox and then do `make html`.
You can then preview the html files in `docs/build/html` with:
```
python -m http.server 8000 --directory build/html
```
...and point your web browser at `http://localhost:8000/`
