Auto merge of #16448 - Young-Flash:typos, r=lnicola

minor: correct typos

I use [crate-ci/typos](https://github.com/crate-ci/typos) to check typos in codebase, if it's ok with you, I'd like to add a typo check CI using [typos](https://github.com/crate-ci/typos) (with Apache-2.0, MIT licenses).

BTW, we can add a [_typos.toml](https://github.com/crate-ci/typos/blob/master/docs/reference.md) as white list for some intentional typos
