Ch 4.2 code block examples with permission annotations use path in tooltips instead of place

[ejohnso49]

• I have searched open and closed issues and pull requests for duplicates, using these search terms:
  • path place
• I have checked the latest main branch to see if this has already been fixed, in this file:
  • https://github.com/cognitive-engineering-lab/rust-book/blob/main/src/ch04-02-references-and-borrowing.md

URL to the section(s) of the book with this problem:

• https://rust-book.cs.brown.edu/ch04-02-references-and-borrowing.html#mutable-references-provide-unique-and-non-owning-access-to-data
• Also applies to other sections with the dynamic annotation to the code blocks

Description of the problem:
In previous issues/PRs (#176 cognitive-engineering-lab/rust-book#211) the wording was changed to move to the use of place over path, however these same changes were not applied to the components used to annotated the code blocks. In particular the tooltips still refer to paths instead of places so it felt confusing to see that term when it is not used elsewhere in this chapter.

Suggested fix:
Change the tooltips and any parts of the permission annotation components to use place instead of path. I really like the annotations, I just got confused with the mixed use of path and place

Thanks for pointing this out. We'll update this in Aquascope.

Will be fixed in #144.
