Posts, Post Types: Remove title attribute from the_shortlink().

Since [13683], `the_shortlink()` has included a `title` attribute. By default, that gives the sanitized post title, and it does not sanitize custom text. Given the low value of this attribute, this changeset removes it.

Props sabernhardt, audrasjb, joedolson.
Fixes #62838.
See #24766.
