[PATCH] oe.patch: fix Git note identity in commitIgnored

[roy@0xbadcaffe.dev]

From: Roy Cohen <roy@0xbadcaffe.dev>

GitApplyTree.commitIgnored() passes the Git user name and email
as positional arguments to addNote(), incorrectly assigning them
to value and commituser.

Pass these as keyword arguments to ensure Git notes can be created
without relying on global Git configuration.

Add a regression test verifying the note content and Git identity.

Fixes [YOCTO #15989]
