fix(deps): bump luv to 1.48.0-2

close #27678

Return a userdata wrapper around the uv_req_t to allow it to be garbage collected before the program exits.
Previously, the returned userdata held a reference to itself in the Lua registry, meaning it would never be able to be garbage collected until the process ended.

This reverts commit 0e4a895, which attempted a workaround for the same underlying problem, but introduced a use-after-free.
