x/pkgsite: deprecated functions do not present a ¶ link at the doc site

[kortschak]

What is the URL of the page with the issue?

https://pkg.go.dev/runtime but any page with a deprecated label will do.

What is your user agent?

Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:109.0) Gecko/20100101 Firefox/113.0

Screenshot

A screenshot will not capture the issue because the ¶ requires a mouse over to appear (this in itself hampers discovererability, but I'm resigned to websites being glossy and non-accessible nowadays).

What did you do?

Navigate to a page with a deprecated function and scroll to the docs for the function. In the example, CPUProfile

Attempt to get a link to a deprecated function to use in an email. This was in the context of wanting to discuss the deprecation.

Note that the link is available in the ToC, but this requires losing context to get the link.

What did you expect to see?

A ¶ link to the function's doc entry as exists for non-deprecated functions.

What did you see instead?

No link mark, only an option to hide the doc.
