# 🔍 Description
This PR makes `javax.servlet` and `jakarta.servlet` co-exist, by introducing `javax.servlet-api-4.0.1` and upgrade `jakarta.servlet-api` to 5.0.0. (6.0.0 requires JDK 11)
Spark 4.0 migrated from `javax.servlet` to `jakarta.servlet` in SPARK-47118 while Kyuubi still uses `javax.servlet` in other modules, we should allow them to co-exist for a while.

### _Why are the changes needed?_
- Change hardcoded Scala's version 2.12 in Maven module's `artifactId` to placeholder `scala.binary.version` which is defined in project parent pom as 2.12
- Preparation for Scala 2.13/3.x support in the future
- No impact on using or building Maven modules
- Some ignorable warning messages for unstable artifactId will be thrown by Maven.
