Add a Kiota generated Java SDK

[andreaTP]

Hi @kfcampbell and @nickfloyd 👋 ,

after the work we have done in Kiota on Java it would be great to start distributing a Java SDK 😄
Here I started to spearhead the effort, but it will require some help on your side to be finalized, e.g. creating the java-sdk repository.

The generated code can be compiled using Maven with a minimal pom.xml like:

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <groupId>com.github.api</groupId>
    <artifactId>github-java-sdk</artifactId>
    <version>0.0.1</version>
    <properties>
        <kiota.libs.version>0.12.1</kiota.libs.version>
        <jakarta.annotation.version>2.1.1</jakarta.annotation.version>
    </properties>
    <dependencies>
        <dependency>
            <groupId>com.microsoft.kiota</groupId>
            <artifactId>microsoft-kiota-abstractions</artifactId>
            <version>${kiota.libs.version}</version>
        </dependency>
        <dependency>
            <groupId>jakarta.annotation</groupId>
            <artifactId>jakarta.annotation-api</artifactId>
            <version>${jakarta.annotation.version}</version>
        </dependency>
    </dependencies>
</project>

Happy to answer any questions and assist in the process!

Thanks for putting this together! A couple of comments.

Suggested change

	- name: Install kiota
	run: dotnet tool install --global Microsoft.OpenApi.Kiota --prerelease

[baywet]

Suggested change

	- uses: actions/setup-dotnet@v4
	with:
	dotnet-version: '8.x.x'
	- uses: microsoft/setup-kiota@v0.5.0

I'm happy to go in the direction you are proposing, but, currently, the installation of the tools is based on dotnet tool install, if we move to the specific GH Action it would be best to update all of the jobs.
Looking for the maintainers of this project guidance here.

cc. @baywet this seems to be a viable workaround for microsoft/kiota#4151 I think we should apply it to the Go generation script as it's affected too.
