[IMP] ir.actions.server: cleanup, sync and spellcheck inline doc

- sync both versions of the doc
- spellcheck/unify the wording, capitalization, etc.
- "Odoo" is not a person, and using it in documentation sentences is
generally redundant and weird, unless there is a real ambigiuty.
By default, it's clear that everything we're talking about is
Odoo-related.
