SOLR-15685: Add Devcontainer to make building easier

[TheSench]

https://issues.apache.org/jira/browse/SOLR-15685

Description

This PR adds a .devcontainer, which provides a Docker Perl/JDK11 build environment. This can be used for new/infrequent contributors to quickly get up and running without needing to install any build tools.

Solution

Using VSCode's Remote Development extension to add the Perl .devcontainer (includes Perl 5). I then updated the auto-generated Dockerfile to include the Java 11 JDK. With these changes, I am able to assemble Solr inside a Docker container without needing to install any other build tools on my machine.

Tests

I started up the container and ran gradlew assemble inside of it. Once the build finished, I ran the generated bin/solr to verify that Solr was able to start.

Not sure what the proper way to proceed is regarding the license in the common-debian.sh script that gets autogenerated. It is licensed under the MIT license. If this change is not something we want to add, I think the proper alternative would be to add .devcontainer/ to the .gitignore so that individual developers can choose to use one without accidentally committing it.
