Fix setting projection axis orientation with a simple way

[rldhont]

By working on using Proj4rs instead of Proj4js #5799, we found a simple way to set axis orientation of some projection.

The backport to release_3_8 failed:

The process '/usr/bin/git' failed with exit code 1

To backport manually, run these commands in your terminal:

# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add .worktrees/backport-release_3_8 release_3_8
# Navigate to the new working tree
cd .worktrees/backport-release_3_8
# Create a new branch
git switch --create backport-5812-to-release_3_8
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick 378effc5a3a4533a3a140d7bc16969070b11b3a1
# Push it to GitHub
git push --set-upstream origin backport-5812-to-release_3_8
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-release_3_8

Then, create a pull request where the base branch is release_3_8 and the compare/head branch is backport-5812-to-release_3_8.
