Switch back to eval_rst

Replaces occurences `{eval-rst}` occurences with `eval_rst` across
manuals. The former is used with myst parser the latter with recommonmark.
Myst parser version is currently worse because it does not link other pages
referenced in text correctly. It treats them as anchors on the same page.
