fix sbt/scala cache key (actions#478)

 The action has a built-in functionality for caching and restoring dependencies. It uses [actions/cache](https://github.com/actions/cache) under hood for caching dependencies but requires less configuration settings. Supported package managers are gradle, maven and sbt. The format of the used cache key is `setup-java-${{ platform }}-${{ packageManager }}-${{ fileHash }}`, where the hash is based on the following files:
 - gradle: `**/*.gradle*`, `**/gradle-wrapper.properties`, `buildSrc/**/Versions.kt`, `buildSrc/**/Dependencies.kt`, and `gradle/*.versions.toml`
 - maven: `**/pom.xml`
-- sbt: all sbt build definition files `**/*.sbt`, `**/project/build.properties`, `**/project/**.{scala,sbt}`
+- sbt: all sbt build definition files `**/*.sbt`, `**/project/build.properties`, `**/project/**.scala`, `**/project/**.sbt`
 
 The workflow output `cache-hit` is set to indicate if an exact match was found for the key [as actions/cache does](https://github.com/actions/cache/tree/main#outputs).
