Simplify copy-pasting workflow

[SakshayMahna]

Current workflow for copy-pasting:

1. Copy the content in local system.
2. Go to VNC browser, expand the tab on left.
3. Select the clipboard button and paste the copied content.
4. Inside the VNC system use the paste functionality.

This involves a lot of steps. To simplify this.

To look into KasmVNC through this issue:
Tiryoh/docker-ros2-desktop-vnc#150

This may allow direct clipboard access and drag-drop file functionality for chromium based browsers (Edge and Chrome) helping quite a lot on Windows.
