Add documentation for geography field types (GeographyPoint, GeographyLineString, GeographyPolygon, GeographyGeometryCollection), spatial filter operators (intersects, dwithin, distance, contains, within), GIST index support, and a guide for upgrading existing projects to use PostGIS.
Rename 04-upgrade-to-postgis.md to 05-upgrade-to-postgis.md to avoid a collision with the existing 04-archive/ directory in the upgrading section.

Thank you, @charlesarchibong, for this great contribution!
Sorry for the wait.
This seems accurate and is well-written. Just a couple of nit comments added.

Thanks for the thorough review, @Swiftaxe! Addressed all four: merged the latest main and moved the upgrade guide into 11-upgrading, dropped the em dashes, and added the SEO frontmatter to both new pages. |
- Add SEO frontmatter descriptions to the geography fields and upgrade-to-PostGIS pages, matching the new convention. - Replace em dashes with parentheses in the GeographyGeometryCollection description.
