`mops publish` rejects `[moc]` section even though it is documented in mops.toml

[fspreiss]

mops publish (mops CLI: 2.12.2) fails with Error: Unknown config section [moc] when the package's mops.toml contains a [moc] section, even though [moc] is a documented and supported section according to the mops.toml reference.

This forces publishers to either:

• remove the [moc] section from mops.toml before every publish (and optionally re-add it afterward), or
• drop the section entirely and lose the local mops check / mops test / mops build configuration it provides.
