"Permission denied" on Unix when generating a font

[Friedrich von Never]

See this commit: https://github.com/ForNeVeR/O21/blob/a981a8cf00733f89895dbd804ae7ae7eb01d1369/O21.Game/O21.Game.fsproj

This yields the following output on Linux or macOS:

  Restore was successful.
  /tmp/O21/O21.Game/Resources/Inter.spritefont
        Building Font /tmp/O21/O21.Game/Resources/Inter-Regular.otf
  /usr/bin/sh: 2: /tmp/MSBuildTempfornever/tmp6cfe20b3b5ef4fe4bc2f55d30ce23a79.exec.cmd: Resources/Inter.spritefont: Permission denied

The issue seems to be in the ; that somehow got added to the end of the item list (even if it shouldn't):
