Metadata preparation log was wrong indent

[sbidoul]

Description

With pyproject.toml:

❯ pip install -e ./pkga
Obtaining file:///home/me/tmp/pkga
  Installing build dependencies ... done
  Getting requirements to build editable ... done
    Preparing editable metadata (pyproject.toml) ... done
    Build backend does not support editables, falling back to setup.py egg_info.
    Preparing metadata (setup.py) ... done
...

Without pyproject.toml:

❯ pip install -e ./pkga
Obtaining file:///home/me/tmp/pkga
    Preparing metadata (setup.py) ... done

Notice the indent of the metadata preparation steps. With pyproject.toml, they appear to be "inside" Getting requirements to build editable, which is not correct as metadata preparation is done after that step. Without pyproject.toml, the indent is 4 characters instead of two.

Expected behavior

Dedent metadata preparation log entries.
