Add GitHub workflow to publish a release

[OptimumCode]

Part of #94

The workflow uses nexus-actions to manage the staging repository. The publication was updated to use the new URL for deployment when a staging repository ID is available.

The following secrets should be added to the project:

• SONATYPE_USERNAME
• SONATYPE_PASSWORD
• SONATYPE_STAGING_PROFILE_ID (can be obtained using this link: https://oss.sonatype.org/#stagingProfiles;$staginProfileId)
• SIGNING_KEY_ID
• SIGNING_KEY
• SIGNING_PASSWORD

@aSemy @krzema12 Could you please take a look at the changes when you have time? Unfortunately, I don't have an OSS account (only OSS1) and cannot test the workflow by myself. But if you have any issues when trying to publish a new release I will be happy to help

Ack, thank you 🙇 In my queue.

[aSemy]

Incredible, thanks!

[krzema12]

Great job, thanks :) I'll configure all the secrets within a day or two, and give it a spin to publish some dummy patch version.

I see that the benchmarks workflow is failing, doesn't seem related to this PR, so I'll take a look as well.

It cannot import the action to validate the Gradle wrapper. It only finds the class with _Untyped suffix.

Ah ok, so this breaking change is by design: https://kotlinlang.slack.com/archives/C02UUATR7RC/p1723929533809109
I'll take care of it.

Thanks @OptimumCode, merging so that the workflow appears in the list of workflows, and I can test it with the secrets set.

Thank you @krzema12. Let me know if you have any issues with the publication
