`@see` tag doesn't render the entity it refers to

[sandersn]

#39760 just went in, but doesn't render the new tag to quick info correctly.

Code

/** @see x it is cool */
const y = 1

Expected behavior:
Quick info renders "@see x — it is cool"

Actual behavior:

Quick info renders "@see — it is cool"

@Kingwl we forgot to test the quick info rendering -- since the entity name is no longer part of the comment text, it doesn't render anymore.
