[PATCH] docs: reporting-issues: Remove reference to oldnoconfig

[Ismael Luceno <ismael@iodev.co.uk>]

Replace it with olddefconfig. oldnoconfig didn't do what the document
suggests (it aliased to olddefconfig), and isn't available since 4.19.

Ref: 04c459d20448 ("kconfig: remove oldnoconfig target")
Ref: 312ee68752fa ("kconfig: announce removal of oldnoconfig if used")
