Revert "docs: Raise minimum pahole version to 1.26 for KF_IMPLICIT_ARGS kfuncs"
This reverts commit 9edd04c4189e047d4b4f6efd1255e2a32cb167b8.
The doc-only change is insufficient. The actual fix requires bumping the
minimum pahole version to 1.27 with proper Kconfig and Makefile.btf
changes, and should be routed through the BPF tree.
