Publish Godot OpenXR Android libraries to MavenCentral

[m4gr3d]

Tracks the progress for making Godot OpenXR Android libraries available to end-users via MavenCentral, a repository provided by the Maven community which contains a large number of commonly used libraries.

This will enable access to the Godot OpenXR Android libraries through a single line addition to the gradle build file:

dependencies {
    ...
    implementation 'io.github.m4gr3d:godot-openxr:<versions>'
    ...
}

The implementation will go through the following steps:

• Setup logic to publish the Godot OpenXR Android libraries to MavenCentral: Add logic to publish the Godot OpenXR Android library to MavenCentral #188
• Create GodotVR's own set of sonatype credentials
• Automate publishing of the Godot OpenXR Android libraries to MavenCentral through github workflows
• Update OpenXR Android related documentation accordingly.

@m4gr3d I noticed it is published on MavenCentral but pointing to your fork. If thats intentional happy for it to be that way but if not, just thought I'd mention it :)

edit Ah i already asked you about it on the PR, never mind :)
