Ignore all git files in artifacts

As these failures are random, I don't see any in the downstream pipelines https://git.drupalcode.org/project/gitlab_templates/-/pipelines/294706.

It'd be great if someone can test this: https://project.pages.drupalcode.org/gitlab_templates/info/testing-mrs/

I would suggest limiting this to just the vendor folder. As other users Kay a dialog need the git folder outside of vendor as part of their custom processes.

Here's a test on Scheduler
https://git.drupalcode.org/project/scheduler/-/pipelines/296921

There wasn't any difference in the Composer (current) job
Before

.: found 68515 matching artifact files and directories 
.git: excluded 1 files                             
.git/**/*: excluded 112 files

After

.: found 68517 matching artifact files and directories 
.git: excluded 1 files                             
.git/**/*: excluded 112 files                      

But in 'Composer Next Major' there were more files ignored
Before

.: found 84976 matching artifact files and directories 
.git: excluded 1 files                             
.git/**/*: excluded 112 files                      

After

.: found 82397 matching artifact files and directories 
.git: excluded 1 files                             
.git/**/*: excluded 112 files                      
**/.git: excluded 4 files                          
**/.git/*: excluded 48 files                       

Agree on #4. Let's be less restrictive for now.

As per #5, if there are no "curl" errors on the composer step, it's most likely that the before and after are always the same. It's one of those issues that only happens randomly, when we hit the "curl" error, so it's going to be difficult to replicate at will.

Checked the downstream pipelines and again, it did not happen. But the MR is still ready for review as I think this will at least fix the 413 Request Entity Too Large side of things.

The latest change did make a difference, the Next Major no longer finds more files to ignore. We get

: found 82427 matching artifact files and directories 
.git: excluded 1 files                             
.git/**/*: excluded 112 files

I'm happy for this to be RTBC although I don't really know enough to say for sure whether it will solve the problem. But you may as well merge this and we'll see.

Merged.

Updated title and description slightly to reflect the solution.
