[17.0][kpi] FIX KPI module warning

[gustavorangel121]

reporting-engine/kpi/views/kpi_views.xml

Line 75 in fcc1e2b

<field name="company_id" group="base.group_multi_company" />

During the installation of the kpi module, I'm getting the following error:

**odoo.addons.base.models.ir_ui_view: attribute 'group' is not valid. Did you mean 'groups'?
View error context:
{'file': '.../kpi/views/kpi_views.xml',
'line': 8,
'name': 'kpi.filter',
'view': ir.ui.view(3470,),
'view.model': 'kpi',
'view.parent': ir.ui.view(),
'xmlid': 'view_kpi_filter'}
**

The line to be fixed:
<field name="company_id" group="base.group_multi_company" />

to:

<field name="company_id" groups="base.group_multi_company" />
