Log Message:
geography/proj: Update to 9.8.1

(Actually, the update was committed with the gdal update by mistake.
This commit adds a comment to proj's Makefile and documents the
update.)

Upstream NEWS, less minor fixes:

## 9.8.1

### Warning

It was discovered after the PROJ 9.8.0 release that several EPSG updates introduced
after EPSG v12.033 - notably the introduction of national realizations of ETRS89
(ETRS89-XXX […] where XXX is the 3-letter ISO country code) - caused backward
incompatibilities in some workflows involving the ETRS89 CRS.

In particular, transformations between ETRS89 and national CRSs based on other
datums are known to be affected for Austria, Belgium, Catalonia, the Netherlands,
Romania, and Serbia. See #4736 for more details.

While we intend to resume tracking the latest EPSG releases in future PROJ
versions, the safest solution identified so far to address these regressions is to
**revert the EPSG related content of its database from EPSG v12.049 to v12.029**,
where v12.029 was the version distributed with PROJ 9.7.1

As a consequence of this revert, the EPSG datum and CRS records introduced in
PROJ 9.8.0, which are mostly related to the new ETRS89-XXX datum and CRS, are no
longer available in PROJ 9.8.1.

### Updates

* Database: **Revert content from EPSG v12.049 to v12.029** (#4741).
  See above warning for more details.

### Bug Fixes

* Chain vertical CRS transformations through intermediate same-datum vertical CRS (#4711)
  Helps for example for **EPSG:5705** (Baltic 1977 height) to **EPSG:5706** (Caspian depth)
  by using intermediate operation from Baltic 1977 height to Caspian *height*
