Update formatting script

Motivation:

The formatting script only checkes Sources and Tests. The Plugins and
directory are currently not checked. Moreover the formatter
is using the 5.9 version.

Modifications:

- Update the formatter to use 5.10
- Upadte the formatting script to check Plugins
- Run formatter

Result:

Formatting checks more places
