Add "start terminal" command to right-click context menu

Context menu when I click on empty space currently has these two options:

would be nice if it had option to start a terminal session in that folder

Implementation

Frontend

Implement a open_terminal function in Plataform with an attached command in command.ts.

Web plataforms should ignore this, due to the complexity of adding a remote terminal to web being out of scope for this issue.

Extra feature (future): Add a settings entry that allows overriding the default terminal

Backend

Implement a open_terminal function in file.rs that checks each OS's default Terminal app:

For macOS we can look at iTerm code to check how it reads/sets the default macOS terminal, and fallback to terminal.app if that fails:
https://github.com/gnachman/iTerm2/blob/v3.5.5/sources/iTermLaunchServices.m#L212-L246

For Windows we can look at Microsoft Terminal code to check how it reads/sets the default Windows terminal, and fallback to Powershell if that fails or to CMD.exe as last case resort:
https://github.com/microsoft/terminal/blob/v1.22.2912.0/src/propslib/DelegationConfig.cpp#L158-L213

For linux there are a couple of ways for configuring the default terminal:

• Look into the $TERMINAL envvar
• For debian based distros run: update-alternatives --query x-terminal-emulator
• For XDG complient DEs check the handler for x-scheme-handler/terminal mime
• For DE specific configurations, see xdg-terminal implementation
• Fallback to a list of default terminals: gnome-terminal konsole xfce4-terminal xterm urxvt lxterminal mate-terminal
