Poetry deprecated self show, and it needs to be updated in Habushu.

For example:

[INFO] Executing poetry command: poetry self show plugins
[INFO] Executing poetry command: poetry self show --outdated
[ERROR] Error: Invalid output format. Supported formats are: json, text.
[INFO] Plugin status could not be determined. This is normally a race condition on another thread touching poetry's underlying pyproject.toml, trying one more time...
[INFO] Executing poetry command: poetry self show --outdated
[ERROR] Error: Invalid output format. Supported formats are: json, text.
