Auto increment version after release.

Description

Adds a workflow that increments the version in build.gradle whenever a new X.Y.Z.0 tag is pushed.

• Successful run: https://github.com/dblock/job-scheduler/actions/runs/1684035495
• PR: [AUTO] Incremented version to 1.2.5. dblock/job-scheduler#1

The idea is that every repo can have its own version of this to increment a patch release. When, for example, 1.2.3 is released and tagged, every repo would automatically get a PR to increment the version to the next development iteration on the release branch (e.g. 1.2). These jobs would fail until a -SNAPSHOT build of OpenSearch is available, which is already automated. One would come to this PR, re-run the CI, and merge on green.

This is identical to opensearch-project/common-utils#106.

Notes

The version is removed from ci.yml because the workflow is not allowed to push a change to workflows without a different access token. You get this error.

To https://github.com/dblock/common-utils
   ! [remote rejected] HEAD -> create-pull-request/patch (refusing to allow a GitHub App to create or update workflow `.github/workflows/ci.yml` without `workflows` permission)
  error: failed to push some refs to 'https://github.com/dblock/common-utils'

We can just use the default in build.gradle.
