[cuegui] Add dynamic version fetching for the CueGUI About menu (Acad…

…emySoftwareFoundation#1517)

- Implemented new configuration options in cuegui.yaml:
- `cuegui.use.custom.version`: Toggle between using VERSION.in or custom
CueGUI version.
- `cuegui.custom.cmd.version.stable`: Command to fetch stable version
(`setenv OPENCUE_BETA 0`)
- `cuegui.custom.cmd.version.beta`: Command to fetch beta version
(`setenv OPENCUE_BETA 1`)
- Modified Constants.py to fetch version dynamically based on config.
- Updated MainWindows.py to display the correct version (stable or beta)
in the About menu.
- Fallback to VERSION.in if custom version is disabled.
