[svg export] note head and stem apart on downstem notes

Already reported and fixed.
See #107081: SVG export leaves space between stems and heads

This bug was created by my last PR which fixed stuff for Tablature.
The problem is that 1227 / 1000 = 1, not 1.227 in Qt. I have to write the code like this:
1227 / 1000.0, if I want it to equal 1.227
So I will add the .0 to two lines of code and post a PR shortly.
Sorry for the oversight.
Here is the PR: https://github.com/musescore/MuseScore/pull/2758

1227 / 1000 = 1, not 1.227 in Qt
That's not just Qt, that's the case in C++ (and in plain old C).
1227 and 1000 are both integers, so the result of the operation will be an integer as well. Making one of them a float will result in the other one being promoted to match and the end result being a float as well.
Strictly speaking only the decimal point is required, (1227 / 1000.), but adding the trailing zero makes it more readable imo.
