build: ensure that MSI installer file name starts with hale-studio

Until now, file names of the MSI installer hale»studio followed the pattern

    HALE-<version>-<language>-<arch>.msi

Change this to

    hale-studio-<version>-<language>-<arch>.msi

but do not change the file names of MSI installers for other products.
