[FIX] l10n_id: show kode transaksi outside accounting

Currently the field `Kode Transaksi` can be found inside the accounting tab. This fix will move it under the tax field. `Kode Transaksi` is a field that should be used in the sale flow and is currently unavailabe for sales team.

Steps to reproduce:
-------------------
* Install **l10n_id**
* Create a company with indonesian localization
* Switch to that company
* Creat a contact
* Toggle the checkbox next to `Tax ID`
* Under the `Accounting` tab, you can find `Kode transaksi`. Sales team don't have access to the accounting tab, and thus not to `Kode transaksi` either.

Why the fix:
------------
Technically what we want here is to have the field for `Kode Transaksi` after the `vat` field from this view

https://github.com/odoo/odoo/blob/04593b265b765f7a6ee079f21bad6a1cf0e5d094/odoo/addons/base/views/res_partner_views.xml#L205-L210

Two possible solutions for this fix:
* Fetch the path to `group/group` and put the field inside.
* Fetch the path to the `vat` field and put the field after. This would also require to change the priority of the view starting from saas-16.3 because the `vat` field is being moved in this view:

  https://github.com/odoo/odoo/blob/8ccde3f101cdb6ca41fe29cc5b4252f13745774a/addons/base_vat/views/res_partner_views.xml#L14-L18

  By changing the priority, it would allow for `Kode transaksi` to be place after the `vat_vies_container`. Else it would be inside, which does not make sense inthis case.
