[FIX] web_editor: fix media_dialog layout

Since BS5 migration [1], `form-inline` and `custom-control` classes are
no more available.

So we use `row` and `col` instead.
Also, we have unwrapped `input-group-append` has it's not more required
in BS5. [2]

Refs:
[1] odoo/odoo#95450
[2] https://getbootstrap.com/docs/5.1/migration/#forms

closes odoo/odoo#95725
