[BUG] Extension does not allow serial monitor or board selection in remote development

[haebler]

Describe the bug
When I start VS code on my Debian ARM SBC (OPi5b), I can install the extension just fine on that system. Board selection or serial monitor opening will fail though.

To Reproduce
Steps to reproduce the behavior:

1. Install Extension on remote Linux host (SSH)
2. Plug MCU with CircuitPython into the USB port on the remote Linux host
3. Try to select the board
4. Error "command 'circuitpython.selectBoard' not found" is shown
5. Try to start "CircuitPython: Open Serial Monitor" results in "command 'circuitpython.openSerialMonitor' not found"

Expected behavior
Expectation is to have those commands working on a remote setup (ssh) as well.

Screenshots
If applicable, add screenshots to help explain your problem.

Desktop (please complete the following information):

• OS: Windows (local) and Armbian (remote)
• Version Windows 11, Armbian Bookwork/sid

Additional context
Seems like there are commands missing in the remote installation of the extension.
