[IMP] hr_recruitment: remove grey area around mail text content

The commit includes changes to the email layout template. The existing template
id `mail_notification_light` has been replaced with a template id
`mail_notification_light_without_background`. This template adds a white
background color to the table element within the email notification, enhancing
the visual appearance.
