sbt 1.12.6 gets stuck trying to resolve sbt-site 1.4.1

## steps

### project/plugins.sbt

```scala
addSbtPlugin("com.typesafe.sbt"      % "sbt-site"    % "1.4.1")
```

### build.sbt

```scala
// empty
```

## problem


Stays in "update" steps forever
```
| => logging-library-build / update 464s
```

## expectation

Works fine with 1.12.5

## notes

sbt 1.12.6
java 21.0.9
Both macOS and Linux (GHA)
