Rollup merge of #71396 - DeeDeeG:improve-e0308-again, r=estebank 
Improve E0308 error message wording again

Hello again,

I recently did this PR: #70242

I felt the error message could be further improved, so I made [a post on the Rust community forum](https://users.rust-lang.org/t/looking-for-feedback-on-an-improved-error-message-for-e0308/40004) to ask for feedback.

(Also, there were some comments on my original PR that I took into consideration as well.)

This PR is my attempt to take all the feedback into account and propose a better and simplified error message that should still be accurate. Its main benefit is having simpler grammar, and hopefully being easier to read and understand.

Thanks to everyone who commented and gave feedback, and thank you for taking a look at this PR.
