The contrib files are minor versioned.  PostGIS is micro versioned.

So we have for example postgis--3.3.0--3.3.1.sql
Also we have 5 extensions we ship all micro versions, so multiply that issue by 5

postgis
postgis_raster
postgis_topology
postgis_tiger_geocoder
postgis_sfcgal

The other wrinkle we have that I don't think postgresql's contrib have is that we support
Each version across multiple PostgreSQL versions.
So for example our 3.3 series supports PostgreSQL 12-15 (with plans to also support 16).
