[Github] fix libc documentation path

[nickdesaulniers]

Running ninja docs-libc-html produces content in {build_dir}/libc/docs, not
{build_dir}/docs. Presubmit jobs for "Test documentation build" were failing as
a result of commit 97f94af ("[Github] Upload built docs as artifact from
test build docs job (#118159)")

I'm not sure if this issue is more pervasive than just libc, or if we should perhaps change something about how we build the libc docs (where they wind up in the build dir)?
