Multiple versions of scala libraries detected

[tashoyan]

I get the following warning:

[WARNING]  Expected all dependencies to require Scala version: 2.12.18
[WARNING]  com.sksamuel.avro4s:avro4s-core_2.12:4.0.13 requires scala version: 2.12.7

I wonder why avro4s requires a precise version of Scala.

Tried with avro4s-core 4.1.1 and 4.0.13.
Java 11
Scala 2.12.18

Workaround: exclude Scala libs from transitive dependencies:

    <dependency>
      <groupId>com.sksamuel.avro4s</groupId>
      <artifactId>avro4s-core_2.12</artifactId>
      <version>4.1.1</version>
      <exclusions>
        <exclusion>
          <groupId>org.scala-lang</groupId>
          <artifactId>*</artifactId>
        </exclusion>
      </exclusions>
    </dependency>

I'm not sure how to fix it. If you want to make a PR I will merge and release.

Seems to be Maven only issue.
On the other thread suggested solution was to upgrade: scala-maven-plugin.
2.12.18 is binary compatible with all 2.12 series according to Scala release notes.
I've tested package and assembly with sbt:
scala version 2.12.18 and avro4s-core 4.1.1
No issue whatsoever.
