PR Info

Fix typos on source code and docs using typos cli.

I only left one typo on CHANGELOG.md which I don't know if it's ok to edit, if it is let me know and I add it to the commit.

error: `boths` should be `both`
  --> ./CHANGELOG.md:653:4
    |
653 | // boths yields `Vec<(E::Model, Vec<F::Model>)>`
    |    ^^^^^
    |

Note: Maybe add a workflow to check for typos on pull requests
