Create Maven credential that can be used to automate release processes with GitHub Actions

[lisad]

Some companies use the DTP artifact registered in the Maven repository (https://mvnrepository.com/) in their deploy processes, but the release to the Maven repository has not been automated.

One step required for that is to get a Maven credential that can be used in GitHub Actions . I'll get @jzacsh or @holachuy and @calumcalder's help with setting that up and applying it.

From what I can tell I think we're publishing through OSSRH, which is the 'legacy' path, but there doesn't seem to be official support for publishing via gradle through the new mechanism, so I think we can stick with OSSRH for now.

Docs for adding a new account for OSSRH publishing are here https://central.sonatype.org/register/legacy/. We already have the org.datatransferproject namespace, so once the account is created we just need to contact sonatype to add the account to that namespace.

With the account created and registered to the namespace, the user token should be available through https://oss.sonatype.org (see https://central.sonatype.org/publish/generate-token/)

I've created the account "LisaDusseault" with my DTI email address. Next steps @jzacsh or @holachuy ?

@lisad I'm submitting a request to add you to the namespace via email with Central Support (as described in the instructions at https://central.sonatype.org/register/legacy/#managing-your-project )

Hi @lisad, that should now be granted
