Legal check: GPL licensed javadocs

[anuraaga]

I noticed that the javadoc jars we publish have a legal folder including a GPLv2 with Classpath exception license

https://javadoc.io/doc/io.opentelemetry/opentelemetry-context/latest/legal/LICENSE

This has been the case since v1.7, when we updated our build toolchain from Java 11 to 17 which appears to have that behavior.

I think our artifacts are generally supposed to be Apache-2.0 so want to confirm this is ok. I don't think there is any setting, it just seems to be reality since Java 17.

Context on the change in javadoc

https://bugs.openjdk.java.net/browse/JDK-8259530

It looks like there is undocumented option --legal-notices=none which can restore the old behavior. I don't know which is more compliant :) Appreciate any advice.
