Broken link from Features-3 to CQL2

[jerstlouis]

The link from OGC API - Features - Part 3: Filtering to CQL2 in the normative references is currently broken.

Open Geospatial Consortium (OGC). OGC 21-065r1: Common Query Language (CQL2) [online]. Edited by P. Vretanos, C. Portele. to be published. Available at https://docs.ogc.org/is/21-065r1/21-065r1.html

The correct link is now https://docs.ogc.org/is/21-065r2/21-065r2.html (or better yet: http://www.opengis.net/doc/IS/cql2/1.0).

Related to this, I really wish OGC policy would be to never use the document / revision number, but always the actual "External Identifiers" (e.g., http://www.opengis.net/doc/IS/cql2/1.0) which always correctly reflect the latest minor revisions, and also that the document server would not do a redirect so that the URI in the address bar would remain the external identifier, so that people copying the URL to reference elsewhere keep using the External Identifier.

This is a major source of findability issue whereas search engine indexing never updates to the newer revisions even after several years.

For example, even though CIS 1.1.1 was published in 2019, the result for Google'ing for "ogc cis 1.1.1" is https://docs.ogc.org/is/09-146r6/09-146r6.html which is not CIS 1.1.1, but http://www.opengis.net/doc/IS/cis/1.1 correctly resolves to 1.1.1 (r8).
