Suggest `-Whelp` if `--print=lints` is specified

[lolbinarycat]

Code

rustc --print lints

Current output

error: unknown print request: `lints`
  |
  = help: valid print requests are: `all-target-specs-json`, `calling-conventions`, `cfg`, `check-cfg`, `code-models`, `crate-name`, `deployment-target`, `file-names`, `host-tuple`, `link-args`, `native-static-libs`, `relocation-models`, `split-debuginfo`, `stack-protector-strategies`, `sysroot`, `target-cpus`, `target-features`, `target-libdir`, `target-list`, `target-spec-json`, `tls-models`

Desired output

error: unknown print request: `lints`

  = help: valid print requests are: `all-target-specs-json`, `calling-conventions`, `cfg`, `check-cfg`, `code-models`, `crate-name`, `deployment-target`, `file-names`, `host-tuple`, `link-args`, `native-static-libs`, `relocation-models`, `split-debuginfo`, `stack-protector-strategies`, `sysroot`, `target-cpus`, `target-features`, `target-libdir`, `target-list`, `target-spec-json`, `tls-models`

  = help: use `-Whelp` to print a list of lints

Rationale and extra context

This is a bit intuitive and confused me a while ago

Other cases

This help message should probably show for `--print lint` and any other arg that contains "lint".
