Auto merge of #95355 - dtolnay:ripgreptest, r=Dylan-DPC

Bump the ripgrep commit exercised by cargotest

This update goes from BurntSushi/ripgrep@3de31f7 (Aug 1, 2019) to current master, BurntSushi/ripgrep@ced5b92 (March 21, 2022).

I need this in order to pick up BurntSushi/ripgrep#1722, which picked up BurntSushi/bstr#58, which unblocks #95345. Ripgrep uses the Debug representation of a `BStr` in some of its tests. In old versions of bstr, that used to just use the standard library's `escape_debug()` implementation, so the output ends up being sensitive to whether the standard library renders character 0 as `\u{0}` or as `\0`. The newer bstr always renders character 0 as `\0` and ripgrep's test suite has been correspondingly updated.
