Fix for ! Missing number, treated as zero. error when using Eisvogel template with Pandoc

[khal45]

In section 3, when I tried generating the report PDF with:

pandoc report.md -o report.pdf --from markdown --template=eisvogel --listings

I ran into the following error:

Error producing PDF.
! Missing number, treated as zero.
<to be read again> 
                   \protect 
l.403 \vspace\*

After some digging, I discovered the issue was caused by \vspace\*{2cm}.
Replacing it with \vspace{2cm} resolved the error.

Posting this here in case anyone else runs into the same problem.

Thanks for this heads-up @khal45
