[IMP] mail plugins: improve the naming consistency of plugins

The plugins were named "Odoo-Gmail Plugin" / "Gmail Plugin" and "Odoo-Outlook Plugin" /
"Outlook Plugin". I chose the later version for both plugins consistently.
I also added a reference to both the Gmail and Outlook docs in the main Mail Plugins doc.
