merge upstream changes (#25)

* Add sigxcpu76's fix to force use of light GTK theme

When using Bambu Studio with a dark themed Linux desktop, many of the dialogs appear as white text on a white background (font's correctly invert, but dialogs remain white).

@sigxcpu76 provided a workaround for this in #12 which is to tell the app to use a light GTK theme.  This change incorporates that workaround into the AppImage making the app more usable until such time as proper dark theme support can be added to Bambu Studio.

* Update Containerfile to make it Docker compatible

- Replace COPY command with Docker compatible syntax
- Rename container tag to bambu-studio-builder so as to not confuse with a container that would actually run Bambu Studio
- Add Docker alternative build method (thx @SG-R)
- Update podman syntax to remove unnecessary sudo

* Add check_available_memory_and_disk to BuildLinux.sh

* Fixes #740

Removing check for local or Remote FX virtualized RDP session. The checks below this line already verify if proper OpenGL support is present.
