Issue description

The message of an annotated tag shown in the commit-tab does sometimes not include the last line.
I found that this happens if the message as returned by git cat-file -p tagname does not end in an empty newline.

The use of git cat-file was introduced by #9616
The change specifically introduced a removal of the last line of the git output, claiming there to always be an empty line:

Maybe this could simply be removed, as it seems the complete message gets .Trim()-ed anyways afterwards.

Steps to reproduce

The only way I was able to reproduce (and how I discovered this) is to create a multiline annotated tag on a GitLab Server using the GitLab REST-API.
(Maybe this is an issue with Gitlab too, not sure if the empty trailing line in a annotated tag would be mandatory?)

After fetching the tag on a local clone, GitExtensions would truncate the last line of the message.

Manually verifying using git cat-file -p tagname confirms that the Gitlab REST-Api created tags indeed miss a trailing newline.

Did this work in previous version of GitExtensions?
