How to make 1.22.9 workspaces work on Ubuntu 24.04

[AndreasBergmeier6176]

We have a workspace with multiple modules. All are defined as using golang 1.22.9.

Now in a module, the extension wants to analyze the encompassing workspace.
It seems to do this with the system Go toolchain :( (which is 1.22.2).
As a result it prints a lot of errors:

packages.Load error: err: exit status 1: stderr: go: go.work requires go >= 1.22.9 (running go 1.22.2)

What must I configure so that it uses another toolchain?

And by the way - is there a way of preventing/disallowing it to use the system Golang toolchain? It almost never is correct to use that.
