Release workflow: Wrong version in AutoRevision.txt for v3.0-patch.3

[blabber]

Describe the bug
The release source archive for v3.0-patch.3 contains the following:

cat Freeciv21-v3.0-patch.3/cmake/AutoRevision.txt
f5eab4
v3.0-patch.2

To Reproduce

• Dowload and inspect the release source archive
• Inspect the tag for v3.0-patch.3 which also contains the wrong version info in AutoRevision.txt

Expected behavior
AutoRevision.txt should contain the correct information, like the file content committed in 4c161dc:

e5a21
v3.0-patch.3

Platform and version (please complete the following information):

• OS: FreeBSD 14.0
• Freeciv21 version: 3.0-patch.3

The debug output of the workflow action displays the correct file contents (check step "Run cat cmake/AutoRevision.txt"). That makes this issue even more mysterious.

This is because we run git archive without committing the new AutoRevision file:

git archive --format=tar.gz --prefix=Freeciv21-v3.0-patch.3/ -o $PWD/build/Freeciv21-v3.0-patch.3.tar.gz HEAD
