The `<html>` element of websites had a `data-oe-company-name` attribute which was dead code since a long time. This commit removes it. Some history: - [1] introduced the SEO dialog which suggested the company name as keyword value. That value was retrieved through a `<meta>` which was added in the DOM at the time. - [2] converted the `<meta>` tag into valid HTML code, by introducing `data-oe-company-name`. - [3] suddenly stopped caring about the company name value... but left `data-oe-company-name` as dead code, alongside a JS method reading it (in the SEO dialog class). - [4] removed the JS method dead code by refactoring the whole SEO dialog during the website-in-backend refactoring... but still left the `data-oe-company-name` dead code. This commit finally cleans it. It was judged that not using the company name value (as step [3] decided) is ok.
