[FIX] web: blurry menu dropdown on chrome when zoom != 100%

This rev. disables Popper.js 3d transformation for positioning
bootstrap dropdowns in navbar, as this transformation causes a
rendering issue on webkit-based browsers (the text in the dropdown
is blurry).

See https://github.com/twbs/bootstrap/issues/23590

Note that it has already been disabled for the other menu dropdowns
(user menu, debug menu) by rev. 5373db1.

Another solution would have been to override the default value in
our bootstrap.js extension file, but for dropdowns that aren't in
the navbar, the dynamic positionning could be interesting.

Fixes #33096

closes odoo/odoo#33174
