[Qbs] qbs 3.0.3 released

[Christian Kandeler]

Hello,

we have released qbs 3.0.3 today. Sources, binaries, change log etc can 
be found at https://download.qt.io/official_releases/qbs/3.0.3.
Note that qbs 3.0.2 was skipped due to a release management hiccup. For 
the same reason, the qbs released with Qt Creator 17.0.1 reports its 
version as 3.0.1. Apologies for any possible confusion resulting from that.
