PRs #73062 and #73043 repurposed the `alias` anchor for a new guide for index
and data stream aliases. Previously, this anchor was used for our field alias
documentation.
Repurposing the anchor has caused continuity errors for users selecting
different versions of the ES docs. It could also cause confusion for users with
a `/current/` link to the `alias` page.
This updates the anchor for the alias guide and adds a redirect page to
disambiguate the `alias` anchor.
It also fixes a bread crumb issue for redirects following the 'Modifying your
Data' redirect page.
Closes#77034.
Changes:
* Reuses the same `aliases` object properties in the following API docs:
* Clone index API

* Put legacy index template API
* Put index template API
* Rollover index API
