Replace dockerImagePrefix with configurable sidecar image

[rarkins]

What would you like Renovate to be able to do?

Allow a configurable/deterministic sidecar image to be configured for self-hosted users.

If you have any ideas on how this should be implemented, please tell us here.

Remove dockerImagePrefix as a config option.

Add sidecarImage as a new global config option, defaulting to containerbase/sidecar:x.y.z. It should be used instead during binarySource=docker sidecar executions.

No need to migrate - we should declare it as a breaking change.

Also configure a regex manager to keep sidecar updated within the Renovate repo.

Is this a feature you are interested in implementing yourself?

No

We should also add the version to a const, so we can validate on install|docker mode that the used containerbase version is greater or equal.

Reproduction for regexManager which will update the sidecarImage verison in renovate repo:
RahulGautamSingh-testing/sidecar-image#2

RegexManager:

{
  "$schema": "https://docs.renovatebot.com/renovate-schema.json",
  "regexManagers": [
    {
      "fileMatch": ["config/options/index.ts"],
      "matchStrings": [
        "default: 'ghcr.io/containerbase/sidecar:(?<currentValue>.*)'"
      ],
      "depNameTemplate": "containerbase/sidecar",
      "datasourceTemplate": "docker"
    }
  ]
}

Should both the replacement and regexManager be added in the same PR?

[rarkins]

Yes

[viceice]

use docker datasource instead of GitHub releases, because on a publish failure the image can be missing

[viceice]

also node versioning is wrong. use leave versioning empty to use docker versioning
