add configuration of biome bin in vscode

In the frontend team, we decided to switch from prettier to biomejs
However the extension is looking at the binary which is either in
ui/ or shell-ui/.
Commiting this configuration will make sure that the bin is correctly
detected for most IDE used by the team.
