[PATCH] docs: Makefile: Sort Documentation targets case-insensitively in make help

Avoid case-sensitive sorting when listing Documentation targets in make help.
Previously, targets like PCI and RCU appeared ahead of others due to uppercase
names.

Normalize casing during _SPHINXDIRS generation to ensure consistent and
intuitive ordering.
