chore: remove project segments gate for oss users (#8666)

This change opens up the project segments page to OSS users. They
could navigate to it explicitly before, but would be told it was a
premium feature (which it is not (since 5.5)).

After this, it'll show up in the settings sidebar as for
pro/enterprise, and you'll get the actual segments table instead of
"this is a premium feature" message.
