### What changes were proposed in this pull request? This PR aims to re-upgrade Scala to 2.13.11, after SPARK-45144 was merged, the build issues mentioned in https://github.com/apache/spark/pull/41943 should no longer exist. - https://www.scala-lang.org/news/2.13.11 Additionally, this pr adds a new suppression rule for warning message: `Implicit definition should have explicit type`, this is a new compile check introduced by https://github.com/scala/scala/pull/10083, we must fix it when we upgrading to use Scala 3 ### Why are the changes needed? This release improves collections, adds support for JDK 20 and 21, adds support for JDK 17 `sealed`: - https://github.com/scala/scala/pull/10363 - https://github.com/scala/scala/pull/10184 - https://github.com/scala/scala/pull/10397 - https://github.com/scala/scala/pull/10348 - https://github.com/scala/scala/pull/10105 There are 2 known issues in this version: - https://github.com/scala/bug/issues/12800 - https://github.com/scala/bug/issues/12799 For the first one, there is no compilation warning messages related to `match may not be exhaustive` in Spark compile log, and for the second one, there is no case of `method.isAnnotationPresent(Deprecated.class)` in Spark code, there is just https://github.com/apache/spark/blob/8c84d2c9349d7b607db949c2e114df781f23e438/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/JavaTypeInference.scala#L130 in Spark Code, and I checked `@javax.annotation.Nonnull` no this issue. So I think These two issues will not affect Spark itself, but this doesn't mean it won't affect the code written by end users themselves The full release notes as follows: - https://github.com/scala/scala/releases/tag/v2.13.11 ### Does this PR introduce _any_ user-facing change?
