Replace reference to draft GeoPose standard with reference to fully approved standard

[ghobona]

This building block...

https://opengeospatial.github.io/bblocks/register/bblock/ogc.geo.geopose.basic.quaternion

..appears to reference the Draft Standard.

GeoPose is now a fully approved OGC Implementation Standard.

Please reference this document https://docs.ogc.org/is/21-056r11/21-056r11.html

..instead of the Draft Standard.
