Rollup merge of #85899 - klensy:jsondocck-f, r=Mark-Simulacrum

jsondocck small cleanup

updated `shlex` (there was some fix https://github.com/comex/rust-shlex/commit/6db4704fcad8393dd6947b1d31720327546a84a2)
replaced `lazy_static` with `once_cell`
removed `serde` direct dependency (`serde_json` will pull it)
