[Easy] `cargo collect-metadata` interprets anything behind a comma as a new lint

[blyxyas]

Summary

While reviewing #10283, we stumbled across this bug that added or as a new lint to the "Affected Lints" list.

This happened because there was an "[...], or [...]" in the configuration option documentation.

Reproducer

I tried this code:

    /// Lint: PUB_UNDERSCORE_FIELDS
    ///
    /// Lint "public" fields in a struct that are prefixed with an underscore based on their
    /// exported visibility, or whether they are marked as "pub".
    (pub_underscore_fields_behavior: PubUnderscoreFieldsBehaviour = PubUnderscoreFieldsBehaviour::PublicallyExported),

I expected to see this happen (in the config's documentation):

Affected lints:

• pub_underscore_fields

Instead, this happened:

Affected lints:

• pub_underscore_fields
• or

---

This was fixed by changing that comma to a semi-colon
