protobuf-all-3.12.3.tar.gz tarball differs from the v3.12.3 tag

[jschueller]

the protobuf-all-3.12.3.tar.gz tarball content differs from the v3.12.3 tag (https://github.com/protocolbuffers/protobuf/releases/tag/v3.12.3)

I noticed because some declarations differ between the protobuf-all-3.12.3.tar.gz and the github-generated v3.12.3.tar.gz tarball:

$ mv protobuf-3.12.3 protobuf-3.12.3.all

This diffs seems to come from:
2ae7cf0
which is marked as included in the v3.12.3 tag
so it might be that protobuf-all-3.12.3.tar.gz is generated from a different commit/branch and not the v3.12.3 tag
