Fix docstrings RST markup in `ansible-console` CLI module (#80719)

* 📝🐛 Fix RST list @ `ansible-console` manpage

Said CLI entrypoint docstring is used to construct the corresponding
manpage. `docutils` were producing the following warning with the
current RST markup used there, as follows:

  :36: (WARNING/2) Bullet list ends without a blank line; unexpected unindent.

This change puts a portion of the first list entry on a separate line
which allows the RST parser stomach it without any problems and
produce correct output without gibberish in it.

* 🎨📝 Use RST inline code @ ansible-console doc

The single backtick syntax was causing things to be interpreted as
italics text. The inline code needs double backticks.
