Poor advice on placing section in setup.cfg.

[tmarktaylor]

In the documentation chapter "Using a configuration file" please disregard the example placing a [tool.phmdoctest] section in setup.cfg. Pytest 7 advises a [tool:*] (colon) and discourages use in setup.cfg. I suspect some other tools may use the colon to discover tool configuration sections in setup.cfg.

For the next version of phmdoctest >1.4.0:

• Add advice to prefer the .toml format followed
  by .ini. and finally .cfg.
• Allow[tool:phmdoctest] in *.cfg.
• Allow [tool.phmdoctest] in *.cfg to remain back
  compatible with phmdoctest 1.4.0.

Note that the name of the configuration file is explictly passed to phmdoctest in place of the Markdown file. There is no requirement to place the configuration section in an existing configuration file. It can be placed in a new file.
