what happened

1. Install Biome VSCode extension v2.1.1 in a devcontainer and put it in devcontainer extensions to be auto-installed.
2. Open preferences (Cmd+Shift+P), "format document with..." -> Biome appears twice in the list.
3. Rebuild the devcontainer -> Biome appears another two times every time I rebuild

what is expected

Biome VSCode extension should only appear once in the list of formatters and should not increase every time the devcontainer is rebuilt.
