Add bump-go action

[eternal-flame-AD]

Rel: #699

Current logic:

If the stable Go version does not equal GO_VERSION on master and does not equal the version on the bump-go branch then create or update a PR.

Whether to go for a fully automated release I think let's wait and see for maybe 2 cycles and if minimal intervention is required then we can make this automated. I think this should have already taken off a large portion of wasted time for releases which is waiting for CI to finish..

For a fully automated workflow I think the general idea of what to do next is:

• Pull in updates daily if master is updated but this branch is not.
• Detect a review submission and after some sanity checks (no new pushes to master, etc), merge to master and generate a new tag automatically using the current release infrastructure.

What do you think of this plan? @jmattheis

To test the current solution on actual GH actions, merge, close #701, delete the bump-go branch, then trigger the workflow by dispatch or cron.

Have you considered using renovate / dependabot for this https://docs.renovatebot.com/modules/manager/regex/. I haven't used this specific feature of renovate, but renovate should provide the logic for opening PRs when there is a new version, and updating existing PRs with newer versions. I think the config could look like this

{
  "regexManagers": [
    {
      "fileMatch": ["^GO_VERSION$"],
      "matchStrings": ["^(?<currentValue>\\d+\\.\\d+\\.\\d+)$"],
      "datasourceTemplate": "docker",
      "depNameTemplate": "golang"
    }
  ]
}

We probably could reference the gotify/build image there, so that it would only create a PR when there is a newer gotify/build image. We could then also add renovate to gotify build to update when there are newer golang docker images.

Generally, I'd rather use these tools than custom scripts as they seem easier to maintain, and I think gotify could also benefit from automatic dep updates (at least for the backend).

Yeah makes sense I support this, although you are in a better position to introduce a new tool like this (I think I don't even have the permission to do it).

I've added renovate to gotify/server and gotify/build. It needs configuration in the repo, there we probably have to only whitelist Go / docker, so that it doesn't update the js deps for now.
