documentation bug in diff_str.Rd

[f-rousset]

Dear cli maintainer,

The value field in diff_str.Rd is

\value{
A list that is a \code{cli_diff_str} object and also a
\code{cli_diff_chr} object, see \link{diff_str} for the details about its
structure.
}

so that the documentation page links to itself, and no reference is given to a documentation for the structure of the returned object.

Many thanks for this great package,

F.

Hi I'd like to fix this documentation bug.

I understand the issue here.

My plan:

1. Find the diff_str.Rd file (in man/ directory)
2. Fix the circular reference in the \value{} section
3. Update it to properly reference diff_chr documentation instead of linking to itself
4. Verify the fix renders correctly with ?diff_str

I can submit a PR within 2-3 days.

Can I work on this?

Thanks!
