mermaid/src/diagrams/git/parser/gitGraph.jison
Alois Klink 0dca4d3393 fix(git): support numeric branch names 
gitGraph does not support branch names that start with a number,
because the gitGraph.jison file parses these as NUM (number) instead.

To fix this, I've changed the NUM parser to only accept strings that
end with whitespace (e.g 1234 is a NUM, but 1234abc is not a NUM).
To do this, I had to move the "skip all whitespace" step to the
end of the parser, but this doesn't seem to have caused any issues,
so it's probably fine.
